Fig. 1 is a schematic diagram of internal hardware connection of a frame device according to an embodiment of the present application, where a main control board card is connected to a plurality of service boards. The importance of detecting the internal connectivity of the frame device is self-evident when the frame device is used as the main connecting device of the local area network, and the current detection method for the internal connectivity of the frame device is mainly as follows: and detecting the internal connectivity of the frame device according to the physical state (UP/DOWN) of the cascade port in the main control board card so as to determine whether the frame device operates normally. For example, the internal connectivity of the frame device is detected according to the physical states (UP/DOWN) of the internal cascade port 1, the internal cascade port 2, the internal cascade port 3, and the internal cascade port 4 in fig. 1, so as to determine whether the frame device operates normally. However, this method has limitations, and in some special cases, the physical state of the internal cascade port of the main control board card is UP, and the frame device cannot normally receive and transmit messages. Therefore, the internal connectivity of the frame device is detected only according to the physical state (UP/DOWN) of the cascade port in the main control board card, which may cause abnormal service processing and unnecessary loss to users.
In view of the above technical problems, an embodiment of the present application provides a method for detecting internal connectivity of a frame device, where a main control board card records a message sending port bitmap corresponding to all first internal cascading ports and a message receiving port bitmap corresponding to all second internal cascading ports, compares whether the message sending port bitmap and the message receiving port bitmap are matched, and determines an internal connectivity status of the frame device according to a matching result of the message sending port bitmap and the message receiving port bitmap. Therefore, the method can automatically and effectively detect the internal connectivity condition of the frame type equipment, can not cause abnormal business processing and avoid unnecessary loss to users. For further explanation of embodiments of the present application, the following examples are provided:
as shown in fig. 2, an interactive flow chart of a method for detecting internal connectivity of a frame device according to an embodiment of the present application may specifically include the following steps:
s201, a main control board card acquires all first internal cascade ports and records a message sending port bitmap corresponding to all the first internal cascade ports;
in the embodiment of the present application, as shown in fig. 1, a main control board card includes at least one first internal cascade port, where one first internal cascade port corresponds to one service board card, and the main control board card may send a message to a specified service board card through the first internal cascade port.
In order to detect the internal connectivity of the frame device, a protocol message is defined, and the protocol message becomes a detection message, and is used for detecting the internal connectivity of the frame device, wherein the detection message carries a destination MAC address. For example, the detection message is a MAC-DA message, and the destination MAC address is 01:80:00:00:08:10.
In the process of specifically detecting the internal connectivity of the frame device, the detection message needs to be relied on, and all the first internal cascade ports need to be acquired so as to send the detection message to all the first internal cascade ports, so that any one of the first internal cascade ports forwards the detection message to a service board card corresponding to the first internal cascade port. For example, as shown in fig. 1, the internal cascade ports 1, 2, 3 and 4 are all first internal cascade ports, and the message sending port bitmaps corresponding to all first internal cascade ports are recorded.
S202, a main control board card sends detection messages to all first internal cascade ports, so that any first internal cascade port forwards the detection messages to a service board card corresponding to the main control board card;
for all the first internal cascade ports acquired in the step S201, the main control board card sends a detection message to all the first internal cascade ports, so that any first internal cascade port forwards the detection message to the service board card corresponding to the main control board card.
Specifically, a message sending thread can be created, and the main control board card sends detection messages to all the first internal cascade ports according to a preset period, so that any first internal cascade port forwards the detection messages to the service board card corresponding to the main control board card.
For example, referring to fig. 1, with a transmission period of 60 seconds, the master control board card sends detection messages to the internal cascade port 1, the internal cascade port 2, the internal cascade port 3 and the internal cascade port 4 respectively, so that the internal cascade port 1 forwards the detection messages to the service board card 1 corresponding to the master control board card, so that the internal cascade port 2 forwards the detection messages to the service board card 2 corresponding to the master control board card, so that the internal cascade port 3 forwards the detection messages to the service board card 3 corresponding to the master control board card, and the internal cascade port 4 forwards the detection messages to the service board card 4 corresponding to the master control board card.
After the detection message is sent to all the first internal cascade ports, a completion mark is sent in parallel, for example, the main control board card sends the detection message for 4 times, and the mark records 4.
S203, any service board card judges whether the detection message meets the preset requirement;
after any service board card receives the detection message, it needs to determine whether it meets the preset requirement, and the embodiments of the present application enumerate two implementation manners here:
implementation 1, a BPDU (Bridge Protocol Data Unit, a bridge protocol data unit is a spanning tree protocol hello packet, which may be sent at a configured interval and used to exchange information between bridges of a network) table entry is configured on all service boards of a frame device, so that a packet carrying a certain MAC address may be redirected to a main control board card, for example, a certain MAC address is 01:80:00:00:08:10.
And any service board card analyzes the destination MAC address carried in the detection message and judges whether the destination MAC address carried in the detection message is consistent with the MAC address recorded in the BPDU table entry. Taking the service board card 1 shown in fig. 1 as an example, the destination MAC address carried in the analysis detection message is 01:80:00:00:08:10, the MAC address recorded in the BPDU table entry is 01:80:00:00:08:10, and the detection message can be redirected to the main control board card by judging that the destination MAC address carried in the message is consistent with the MAC address recorded in the BPDU table entry.
Implementation 2, configuring ACL (Access Control List ) rules on all service boards of a frame device may redirect a packet carrying a certain MAC address to a main control board, for example, a certain MAC address is 01:80:00:00:08:10.
Any service board card analyzes the destination MAC address carried in the detection message and judges whether the destination MAC address carried in the detection message matches (hits) the ACL rule. Taking the service board card 1 shown in fig. 1 as an example, the destination MAC address (01:80:00:00:08:10) carried in the detection packet is analyzed, and the ACL rule is used to redirect the packet carrying the destination MAC address (01:80:00:00:08:10) to the main control board card, so that it can be known that the destination MAC address carried in the detection packet matches (hits) the ACL rule, and the detection packet can be redirected to the main control board card.
S204, if yes, any service board redirects the detection message to the main control board through a second internal cascade port;
and (3) aiming at the judging result in the S203, if the judging result is yes, any service board card redirects the detection message to the main control board card through a second internal cascade port corresponding to the service board card.
For example, the service board card 1 judges that the destination MAC address carried in the packet is consistent with the MAC address recorded in the BPDU table entry, so that the detection packet can be redirected to the main control board card, or the service board card 1 judges that the destination MAC address carried in the detection packet matches (hits) an ACL rule, so that the detection packet can be redirected to the main control board card.
It should be noted that, in the embodiment of the present application, the first internal cascade port and the second internal cascade port may be identical or not identical. Meaning that for the same internal cascade port, the internal cascade port is a first internal cascade port in the message sending phase and a second internal cascade port in the message receiving phase.
S205, the main control board card records the bitmap of the message receiving ports corresponding to all the second internal cascade ports, and compares whether the bitmap of the message sending ports is matched with the bitmap of the message receiving ports;
after any service board card redirects the detection message to the main control board card through the second internal cascade ports, the main control board card can receive the detection message, record the message receiving port bitmaps corresponding to all the second internal cascade ports until the main control board card can record the message receiving port bitmaps corresponding to all the second internal cascade ports, and compare whether the message sending port bitmaps are matched with the message receiving port bitmaps.
In view of the corresponding relation between the message sending port and the message receiving port, the main control board card can specifically compare whether the number of ports in the bitmap of the message sending port is matched with the number of ports in the bitmap of the message receiving port, and whether the ports in the bitmap of the message sending port are corresponding to the ports in the bitmap of the message receiving port.
For example, the message sending port bitmap includes: the message receiving port bitmap comprises an internal cascade port A, an internal cascade port B, an internal cascade port C and an internal cascade port D: the corresponding relationship between the message sending port and the message receiving port is shown in the following table 1:
| internal cascade port A | Internal cascade port E |
| Internal cascade port B | Internal cascade port F |
| Internal cascade port C | Internal cascade port G |
| Internal cascade port D | Internal cascade port H |
TABLE 1
As can be seen from table 1 above, the number of ports in the message sending port bitmap matches the number of ports in the message receiving port bitmap, and the ports in the message sending port bitmap correspond to the ports in the message receiving port bitmap.
In particular, in the embodiment of the present application, it is assumed that the first internal cascade port is consistent with the second internal cascade port, and in view of the correspondence between the message sending port and the message receiving port, the main control board fixture specifically compares whether the bitmap of the message sending port is consistent with the bitmap of the message receiving port. For example, the message sending port bitmap includes: the message receiving port bitmap comprises an internal cascade port 1, an internal cascade port 2, an internal cascade port 3 and an internal cascade port 4: the internal cascade port 1, the internal cascade port 2, the internal cascade port 3 and the internal cascade port 4 can know that the bitmap of the message sending port is consistent with the bitmap of the message receiving port.
After the comparison of the message sending port bitmap and the message receiving port bitmap is completed (and whether the port in the message sending port bitmap corresponds to the port in the message receiving port bitmap or not), the flag may be cleared, and the message sending port bitmap and the message receiving port bitmap may be cleared, so as to prepare for the next internal connectivity detection of the frame device.
S206, the main control board card determines the internal connectivity status of the frame device according to the matching result of the message sending port bitmap and the message receiving port bitmap.
Aiming at the matching result of the message sending port bitmap and the message receiving port bitmap in S205, the main control board card can determine the internal connectivity condition of the frame device according to the matching result, which is specifically as follows:
if the number of ports in the message sending port bitmap is matched with the number of ports in the message receiving port bitmap (and the ports in the message sending port bitmap correspond to the ports in the message receiving port bitmap), determining that the internal connectivity of the frame equipment is normal;
if the number of ports in the message sending port bitmap is not matched with the number of ports in the message receiving port bitmap (and the ports in the message sending port bitmap are not corresponding to the ports in the message receiving port bitmap), determining that the internal connectivity of the frame equipment is abnormal, generating an alarm log, recording that the link between the message sending port and the message receiving port is abnormal in the alarm log, and enabling a user to directly check the alarm log to determine an abnormal link.
In the embodiment of the present application, the first internal cascade port is a first internal cascade port in an UP state, and the second internal cascade port is a second internal cascade port in an UP state. In addition, the steps executed by the main control board card may be executed by a CPU on the main control board card, which is not limited in the embodiment of the present application.
Through the description of the technical scheme provided by the embodiment of the application, the main control board card records the message sending port bitmaps corresponding to all the first internal cascade ports and the message receiving port bitmaps corresponding to all the second internal cascade ports, compares whether the message sending port bitmaps are matched with the message receiving port bitmaps, and determines the internal connectivity condition of the frame equipment according to the matching result of the sending port bitmaps and the message receiving port bitmaps. So that the internal connectivity condition of the frame type equipment can be automatically and effectively detected, the abnormal business processing is not caused, the unnecessary loss to the user is avoided,
corresponding to the foregoing method embodiment, the embodiment of the present application further provides a system for detecting internal connectivity of a frame device, where the system includes:
the main control board card acquires all first internal cascade ports and records a message sending port bitmap corresponding to all the first internal cascade ports;
the main control board card sends detection messages to all the first internal cascade ports so that any first internal cascade port forwards the detection messages to the service board card corresponding to the main control board card;

and the main control board card determines the internal connectivity condition of the frame equipment according to the matching result of the message sending port bitmap and the message receiving port bitmap.
The implementation process of the functions and roles of each unit in the above system is specifically shown in the implementation process of the corresponding steps in the above method, and will not be described herein again.
