I'm experiencing a strange issue. I have two Cat4000 L3's running:
IOS (tm) Catalyst 4000 L3 Switch Software (cat4000-I9S-M), Version 12.2(20)EWA4, RELEASE SOFTWARE (fc2)
both with ROM 12.2(31r)SGA1
Both switches were purchased at the same time, have the same image installed from the same TFTP server, and are configured identically with respect to features, SNMP, etc. I even diffed the configs and only vlans, VTP domain, and interfaces are different.
I have a homegrown PHP script that does a SNMP walk, correlates MAC addresses with ports, and then integrates this into our documentation wiki (for all connected devices, the wiki has their MAC addresses, the script automatically updates with switch and port number).
On one switch, I can walk .18.104.22.168.22.214.171.124.4.1.2 (BRIDGE-MIB::dot1dBasePortIfIndex) fine using community string indexing, and I get back correct results. On the second switch, I don't get any results at all, for any VLAN...
Any suggestions? This really has me stumped, granted I'm more of a programmer than a netadmin...
