how to show mac address table on cisco switch

But there are a few cases that I can't find a clear answer too.

If I could find how to do it, I'm not sure how to create a poller that would hit each VLAN on the switch and then add up the MACs.I feel like I have a good understanding of how a switch generally works in most cases.

I think the reason is because you're supposed to specify the VLAN that you want to poll (see Cisco's example above) but I can't find a way to do that in SW.

When testing dot1dTpFdbAddress in SW it only picks up a few MACs on the switch.

I'm hoping that there's a way to create a poller in SW to get the MACs and then add them up, but I'm having two problems: It seems pretty easy to do, but I'm trying to keep it in Solarwinds instead of writing an outside script to do it. There's a discussion about it at this link.

I haven't actually seen an example script, I've just seen people say that they've done it. and so forth for each VLAN discovered in the first step.įrom that point, people talk about writing a script to add up the MACs discovered in each of the VLANs. Nms-server2:/home/ccarring> snmpwalk -c 14.32.6.17 dot1dTpFdbAddress In the example, VLAN 2 contains no entries in the table: Is there a way to do that in SW? Can anyone point me in the right direction?Ģ. For each VLAN, get the MAC address table (using community string indexing) dot1dTpFdbAddress (.1.3.6.1.2.1.17.4.3.1.1). It seems that most people are writing scripts to pull the MAC address count per VLAN and then add it up. Total Mac Address Space Available: 1854 <- I'd like to pull this number but I don't think there's an OID to do it The problem is that there's no OID that I can find that corresponds to those numbers: I've been researching on the Cisco support forums and I see a lot of people writing their own scripts to do it, but I'm trying to keep my network management as centralized as possible, so I'm hoping to do it in Solarwinds.īasically I want to retrieve the bolded lines below. It seems that Cisco has made this unusually complex. I'm trying to figure out a way to poll Cisco switches (3750s and 6509s) for the number of MAC addresses that they are using.
