I have a Cat 4006 switch. There's a couple of devies plugged into the switch that doesn't register its MAC address. When I do 'sh port mod/port', it states connected. But when I do a "sh cam dyn" on the same mod/port, there's no MAC address listed. Anybody know of another way for me to find the MAC? The switch is physicall located in another state so I can't really trace the wire.
Sounds like the cam table has timed out. Unless a packet is sent from the devices, the cam table won't be populated. Any chance you can call and have the cables traced, identify the machine/IP and then ping it? The mac address should show up in your cam table immediately following. Also, you may want to check to see if the duplex settings on both sides are the same. This can keep the connection up on the switch, but down on devices. Let me know how this turns out or if I can provide any further assistance.
We have 3 identical switches configured by someone else and would like to claim some of the Gigabit ports(G1/G2/G3/G4) for use on servers. When we try to change the wiring and configuration, we run in to connectivity issues. Attached is a des...
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
