ciscoUFwUrlfServerStateChange

Module: CISCO-UNIFIED-FIREWALL-MIB

OID (symbolic): CISCO-UNIFIED-FIREWALL-MIB::ciscoUFwUrlfServerStateChange

OID (numeric): 1.3.6.1.4.1.9.9.491.0.1

Node type: NOTIFICATION-TYPE

Description: This notification is generated when the firewall elects a new primary URL filtering server from the existing set of configured servers.

Such a change could occur either as a result of the current primary server becoming unavailable or as a result of explicit management action in nominating a filtering server the primary server.

The notification is issued just before the change occurs. Consequently, the varbinds identify the attributes corresponding to the old primary server.

This notification is issued if and only if the object 'cufwCntlUrlfServerStatusChange' has been set to 'true'.

Examples

Send this trap to an SNMP manager — replace <manager> with the IP or hostname of your monitoring server (SNMPv2c):

snmptrap -v2c -c public <manager> '' CISCO-UNIFIED-FIREWALL-MIB::ciscoUFwUrlfServerStateChange
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.9.9.491.0.1

Listen for incoming traps on the manager host (-f keeps it in the foreground, -Lo prints to stdout — useful for testing):

snmptrapd -f -Lo -c /dev/null authCommunity log public

Example snmptrapd log entry:

zoo11-linux.zoo [UDP: [192.168.30.111]:57906->[192.168.30.10]:162]:
