Below at first explanation is stored in information to be monitored among the MIB and the corresponding relation (following expression) of OID.
| ??node?ID | Node number |
| ??WLANES?SID | The wireless mesh network title |
| ??ath0Mode | Network interface card 1 mode of operation |
| ??ath1Mode | Network interface card 2 mode of operations |
| ?linkBreak | Link State |
| ?coldStart | Router is restarted |
| ?pathToGW | To gateway path |
Below explain in detail each OID content:
1) WLANESSID: the title of the wireless access network that each router is set up, unique distribution in the whole router network is used for this Access Network of unique identification, inserts for all types of user, as IP camera, notebook computer etc.;
2) ath0Mode (ath1Mode): the mode of operation of network interface card, this value is represented to insert for the user for AP, represents to be used for networking during for mesh;
3) linkBreak: expression certain paths state from the router to the gateway.This value puts 1 when certain bar link down, and initiatively sends interrupting information to remote management terminal, and notice management end link is made mistakes;
