Description
Technical Field
The embodiment of the invention relates to the technical field of communication, in particular to a method and a device for packaging a remote port mirror image, electronic equipment and a storage medium.
Background
Mirroring refers to a technology on a network device for copying and transmitting a packet flow passing through a port to a network monitoring device, and the technology is mainly used for monitoring and analyzing a data flow on a switch. The data flow of some ports (hereinafter referred to as mirror source ports) on the switch to be monitored can be copied by using a mirror image technology, and sent to the analysis equipment through the port (hereinafter referred to as mirror destination port) connected with the flow analysis equipment, and network monitoring and troubleshooting can be carried out on the analysis equipment.
The mirror image is divided into an input mirror image and an output mirror image, the input mirror image copies the message input from the mirror image source port to the mirror image destination port and sends the message to the analysis equipment, and the output mirror image copies the message output from the mirror image source port to the mirror image destination port and sends the message to the analysis equipment. After the message is copied, normal forwarding is not influenced.
Remote port mirroring (RSPAN) is an extension of local port mirroring (SPAN) and breaks the limitation that source and destination ports must be on the same device, allowing multiple network devices to be spanned between the source and destination ports. Encapsulating remote port images (ERSPAN) is an extension of remote port images (RSPAN). In the common remote port mirror image, the mirror image data message can only be transmitted in two layers and cannot pass through the routed network, and the mirror image message can be transmitted between the routed networks by encapsulating the remote port mirror image.
The function of the ERSPAN is to encapsulate all mirrored messages into IP messages through a GRE tunnel, and route the IP messages to the destination port of the remote mirroring device. The determination of the mirror image destination port is to obtain which physical port the mirror image goes out through the routing logic according to the configured IP address of the outgoing direction. Unlike SPAN and RSPAN, which specify the egress type by directly configuring the egress instance, ERSPAN determines the egress type by configuring the destination port IP address and looking up the egress instance through routing logic.
In hardware, the method can be realized by directly setting a register of a port based on an input mirror image and an output mirror image of the port. The determination of the mirror image outlet type of the ERSPAN is realized through routing logic, if the outlet direction IP is an aggregation port IP, the installation of the list item of the original scheme fails due to the fact that the chip subtracts TRUNK hardware list items, the return does not support errors, and the function that the ERSPAN mirror image outlet is the aggregation port cannot be effective.
Therefore, how to solve the problem of mirroring the packaged remote port with the aggregation port as the outlet is an important issue to be solved urgently.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic flowchart of a method for encapsulating a remote port image according to an embodiment of the present invention, which is applied to a network device, and as shown in fig. 1, the method includes:
step S11, obtaining configuration information of each packaged remote port mirror image in the network equipment;
specifically, if a packet flow on a network device, such as a switch, is to be monitored, an Encapsulated Remote Port mirror (ERSPAN) may be configured based on a Port configuration or an ERSPAN may be configured based on a packet flow, specifically, an ERSPAN may be configured on a register of a monitored Port (i.e., a mirror source Port) on the network device, or an ERSPAN may be configured on each Port through which a specific data flow that meets a monitoring condition passes, and a hardware resource is installed under the condition that the ERSPAN configuration is complete and a configured flow is generated, so that the packet flow to be monitored is mirrored to a destination Port. In order to solve the problem, in the embodiment of the present invention, first, configuration information of all ERSPAN on a network device is obtained, specifically, the network device may collect configuration information of each port, screen out the ERSPAN configuration information from the configuration information, or actively report the configuration information to the network device after the port is set to be configured to complete the ERSPAN, so that the network device may obtain all the ERSPAN configuration information of itself.
Step S12, according to the configuration information, judging whether the mirror destination port of each packaged remote port mirror image is an aggregation port;
specifically, the network device acquires an IP address of a destination port of each ERSPAN according to configuration information of each ERSPAN; and judging whether the destination port of the corresponding encapsulated remote port mirror image is an aggregation port or not according to the IP address of the destination port. For example, the network device configures an IP address of a destination port through the ERSPAN, finds an egress instance through the routing logic to determine the type of the egress, and in practical application, the network device may store the IP addresses of all AP ports in advance, so as to determine whether the destination port of each ERSPAN is an AP port through comparison.
Step S13, if the mirror image destination port of the first package remote port mirror image is an aggregation port, acquiring a member port of the aggregation port;
step S14, changing configuration information of the first package remote port mirror image, and setting a mirror image destination port in the configuration information as a member port of the aggregation port.
Specifically, if the mirror destination port configured by a certain ERSPAN is an AP port, the network device obtains all member ports of the AP port, for example, the network device may store the member port of each AP port in advance, and monitor the online status of each member port in real time, and if it is determined that the mirror destination port configured by a certain ERSPAN is an AP port, obtain all online member ports of the AP port, that is, available member ports, change the ERSPAN configuration, change an aggregation port in the destination port in the ERSPAN configuration to an available member port of the aggregation port, for example, set the first online member port in the AP port to the mirror destination port of the ERSPAN, and the like, thereby solving the problem that the destination port cannot be supported in the ERSPAN as an aggregation port, and implementing the function of the ERSPAN.
According to the method for encapsulating the remote port mirror image, provided by the embodiment of the invention, after the mirror image destination port of the encapsulated remote port mirror image is judged to be the aggregation port, the destination port is changed into the member port of the aggregation port, so that the purpose that the remote port mirror image is encapsulated to the aggregation port is realized, and the problem that the ERSPAN cannot support the destination port as the aggregation port is solved.
On the basis of the foregoing embodiment, further, the acquiring the member port of the aggregation port includes:
acquiring all online member ports of the aggregation port;
if the number of the online member ports is larger than 1, determining a source port corresponding to the aggregation port and a member port mapping table according to the number of the source ports corresponding to the aggregation port and the number of the online member ports;
correspondingly, the setting of the mirroring destination port in the configuration information as the member port of the aggregation port includes:
and setting the mirror image destination port of each source port corresponding to the aggregation port in the configuration information as the corresponding member port of the aggregation port according to the source port and member port mapping table.
Specifically, if the destination port of the mirror image of the ERSPAN is an AP port, and there are a plurality of online member ports of the AP port, an Equal-Cost multi-path Routing (ECMP) idea may be utilized to implement dynamic mapping to generate a plurality of groups of mirror images, so as to achieve the purpose of balanced output of the mirror image traffic from the AP port. The network device determines a source port corresponding to the aggregation port and a member port mapping table according to the number of the source ports corresponding to the aggregation port and the number of online member ports, and sets a mirror destination port of each source port corresponding to the aggregation port in the ERSPAN configuration information as a member port of the aggregation port corresponding to the mirror destination port according to the mapping table.
For example, fig. 2 is a schematic diagram of a mirror image with an AP port as a mirror image exit according to an embodiment of the present invention, as shown in fig. 2, ports with port IDs 1 to 4 and 6 are all online ports (i.e., an UP state), a port 5 is an offline port (i.e., a Down state), and a port 3 to 4 is an online member port of the AP port. The flow is from 1, 6 ports in to 2 ports out. ERSPAN is configured at ports 1 and 6, a mirror image outlet is an AP port, an aggregation port of a mirror image destination port is converted into a member port of the mirror image destination port, a mapping relation can be made between flow source port information and the member port, a message flow with the source port being the port 1 flows out from a member port 3, and a message flow with the source port being the port 6 flows out from a member port 4. And evenly distributing the source ports to the member ports according to the flow, and adding mapping tables of the member ports mirroring different source ports. And (4) the subsequent different source flows come in, and the AP member port outlet is directly selected by maintaining a mapping table without mapping. In addition, the change information of the source port and the destination port can be managed in real time, the mapping table is updated, and the phenomenon that the mirror image fails after the member port of the AP port is changed is avoided.
On the basis of the foregoing embodiments, further, the acquiring the member port of the aggregation port includes:
acquiring all online member ports of the aggregation port;
if the number of the online member ports is more than 1, calculating hash values of various message flows to be mirrored corresponding to the aggregation port;
determining a hash value and a member port mapping table corresponding to the aggregation port according to the hash value and the number of the online member ports;
correspondingly, the setting of the mirroring destination port in the configuration information as the member port of the aggregation port includes:
and setting the mirror destination port of each message flow to be mirrored corresponding to the aggregation port in the configuration information as the member port of the aggregation port corresponding to the hash value according to the hash value and the member port mapping table.
Specifically, because the number of the ERSPAN source ports and the number of the destination ports may not be equal, in order to achieve a better balancing effect, the ERSPAN source ports and the destination ports may be converted into a flow-based mirror image, hash values of various message flows to be mirrored corresponding to an aggregation port are calculated, the number of the member ports of the AP port is complemented, a plurality of groups of mirror images are generated, the hash values corresponding to mantissas are respectively matched, and the mirror images are mirrored to different member ports. For example, an Access Control List (ACL) may be used to match a hash value of an original packet, and according to the hash value and the number of online member ports of an AP port, a hash value and a member port mapping table corresponding to the AP port are determined, and when the online member ports change, the hash value and the member port mapping table are recalculated to generate, so as to avoid a phenomenon that a mirror image fails after the member ports of the AP port change.
The method for encapsulating the remote port mirror image provided by the embodiment of the invention has the advantages that after the mirror image destination port of the encapsulated remote port mirror image is judged to be the aggregation port, the destination port is changed into the member port of the aggregation port, the purpose of encapsulating the remote port mirror image to the aggregation port is realized, and the purpose of uniformly outputting the mirror image flow of the encapsulated remote port from the aggregation port is realized through the mapping table.
On the basis of the above embodiment, further, the method further includes:
and if the current online member port number of the aggregation port is 0, generating alarm information aiming at the encapsulation remote port mirror image corresponding to the aggregation port.
Specifically, if the number of online member ports of an AP port of a destination port of the ERSPAN is 0, that is, there is no available member port for the AP port, an alarm message is generated, an error is returned, and it is prompted that the aggregation port cannot mirror the message.
Further, if the mirror destination port of the encapsulated remote port mirror is a physical port, processing is directly performed according to the existing ERSPAN, in practical application, the network device may be provided with a physical port mirror module and an aggregation port mirror module, the network device firstly determines that the outlet is a physical port according to the destination port information in the ERSPAN configuration information, and then directly uses the physical port mirror module, and if the outlet is determined to be an aggregation port, the aggregation port mirror module is used. If the physical port mirror image module is used, selecting an optimal physical port according to the ID of the aggregation port through an ECMP algorithm, and mirroring the message stream to the specified physical port through the physical port mirror image module; if the aggregation port mirror image module is used, because of the limitation of a chip, the aggregation port ECMP logic cannot be directly used, the aggregation port mirror image module is quoted, a source port and member port mapping table or a hash value and member port mapping table is introduced, and one member port in the AP member ports is selected as a mirror image outlet, so that the purpose port of the device mirror image of the chip is an encapsulated remote port mirror image of the AP port, other mirror image functions are not interfered, and meanwhile, the equalization method selected by the member ports can be changed according to service requirements and is more flexible than hardware realization.
The method for encapsulating the remote port mirror image provided by the embodiment of the invention has the advantages that after the mirror image destination port of the encapsulated remote port mirror image is judged to be the aggregation port, the destination port is changed into the member port of the aggregation port, the purpose of encapsulating the remote port mirror image to the aggregation port is realized, and the purpose of uniformly outputting the mirror image flow of the encapsulated remote port from the aggregation port is realized through the mapping table.
