Hi,

I found this document which explains the steps for doing snmpwalk to get the MAC info associated with VLAN's and Ports. Is there a script already for this? If no is someone interested in creating it?

do a search for cammer. It was included with MRTG in the contribs folder for a while. There is also a version that uses a mysql backend & php frontend

[neilr]

Thanks I'll look into that.

Hi,

I looked into cammer and unfortunately I'm running a 6500 Catalyst with all layer2 VLAN's (no routing), since cammer requires a router to get the mac-addresses from it will not work for me.

Anyone have any other ideas or suggestions?

Thanks,

You use the address of the router that ties the vlans together. I am assuming
that you are running a router on stick in which the 6500 vlans can talk to one another via an external router.

Code: Select all

perl \cammer\cammer.pl public@10.1.1.10 public@10.1.1.1 >macout.txt

assuming that public is your SNMPReadCommunityString and 10.1.1.10 is your switch and 10.1.1.1 is your Router.

actually, they are not tied together at all, they don't communicate at all, they are not routed at all. hence my issue. The switch is only doing layer2, none of the networks associated with the vlan's are being routed except through NAT/PIX firewall.

I guess I could give it the PIX as the router and see what happens.

hmm,

that actually seemed to work. Here was the output file.
