We briefly lost our MPLS WAN link the other day and since then we have one remote 3750 switch that we can't poll via SNMP. I did a "show ip redirects" on the switch and it does show an incorrect route (to our firewall) back to the SNMP polling station. The question is twofold, how did this entry get there and how can I clear it. I did try the "no ip redirects" command but no luck. There is no IP routing on the 3750. Any ideas on how to get rid of this?
Yes, it seems to be stuck on 10.4.10.1 for some odd reason. Give it a reboot and it should clear it.
Keep in mind to always use a default-gateway in your switch configuration when you aren't running routing on them, and never rely on proxy-arp.
