I have several 2950 switches connected in a chain. On the first one I have a dhcp server and everything is in 1 vlan.
on port 24 I have an uplink to switch 2. On switch 2 i have an uplink to 3. All ports are confiugred the same.
My problem is any pc plugged into switch 2 will not get dhcp.
If i do a sh-mac-address-table add , I see what port its on. If i log into switch one and do a sh mac-address-table it will not show the pc.
Now if i take that same pc and plug it into switch 3 or 4 or 5. and do a show mac-address-table I see it on all the switches like i should. Also, that PC will get a dhcp address.
I cannot figure out why it isnt working on switch 2. But all other switches behind #2 work and the traffic is passing fine.
