Re: SNMP ifEntry

Hi,

If you are asking how to know what is the ifIndex of an interface then:

R1#*sh snmp mib ifmib ifindex*
Serial1/0.14-mpls layer: Ifindex = 12
FastEthernet0/1: Ifindex = 2
Serial1/3: Ifindex = 6
Serial1/1: Ifindex = 4
VoIP-Null0: Ifindex = 7
Loopback0: Ifindex = 10
Null0: Ifindex = 9
Serial1/0.14: Ifindex = 11
SSLVPN-VIF0: Ifindex = 8
FastEthernet0/0: Ifindex = 1
Serial1/2: Ifindex = 5
Serial1/0: Ifindex = 3

Remember to add the following command:

R1(config)#snmp-server ifindex persist

HTH,
