Using the Firewall and Memory Pool MIBs

The Cisco Firewall and Memory Pool MIBs let you poll failover and system status.

This section contains the following topics:

• ipAddrTable Notes, page 9-46

• Viewing Failover Status, page 9-47

• Verifying Memory Usage, page 9-48

• Viewing The Connection Count, page 9-49

• Viewing System Buffer Usage, page 9-50

In the tables that follow in each section, the meaning of each returned value is shown in parentheses.

ipAddrTable Notes

Use of the SNMP ip.ipAddrTable entry requires that all interfaces have unique addresses. If interfaces

have not been assigned IP addresses, by default, their IP addresses are all set to 127.0.0.1. Having

duplicate IP addresses causes the SNMP management station to loop indefinitely. The workaround is to

assign each interface a different address. For example, you can set one address to 127.0.0.1, another to

127.0.0.2, and so on.

SNMP uses a sequence of GetNext operations to traverse the MIB tree. Each GetNext request is based

on the result of the previous request. Therefore, if two consecutive interfaces have the same IP 127.0.0.1

(table index), the GetNext function returns 127.0.0.1, which is correct; however, when SNMP generates

the next GetNext request using the same result (127.0.0.1), the request is identical to the previous one,

which causes the management station to loop infinitely.

For example:

GetNext(ip.ipAddrTable.ipAddrEntry.ipAdEntAddr.127.0.0.1)

1 2 ... 343 344 345 346 347 348 349 350 351 352 353 ... 465 466
