Neil,
Thanks very much for your reply.
I didn't quite understand why you grep '10.10.10.100'. Does it has something to do with transmission(10)in the MIB tree?
I'd like to poll mac addresses from a switch, then consult router arp table to decide the ip address off each switch port. Here is what I did:
(Linux)snmpwalk HOSTNAME STRING@VLAN# 17.5.1.1.1.1.0
17.5.1.1.1.0.2.179.25.236.92.1 = OCTET STRING: Hex: 00 02 B3 19 EC 5C
17.5.1.1.1.0.2.179.25.239.162.1 = OCTET STRING: Hex: 00 02 B3 19 EF A2
......
On the switch,
Switch#sh mac | e 0/4[7|8]$
Destination Address Address Type VLAN Destination Port
------------------- ------------ ---- --------------------
0002.b319.ec5c Secure 105 FastEthernet0/38
0002.b319.efa2 Secure 105 FastEthernet0/12
......
If I could correlate "17.5.1.1.1.0.2.179.25.236.92.1" to "FastEthernet0/38", then I can easily write a script to do what I want on tens of switches. Spent the whole afternoon, still haven't got a clue.
Can you help?
Cheers,
Weidong
