I am having trouble trunking these two switches together. I am running a Here is the following information that I am seeing:
I have a foundry router trunking to the gig port on a 3548. I am announcing the 10.5.0.1/29 off of the virtual interface 7. I have set the mgnt vlan (int vlan 7 )10.5.0.2/29, and can ping across to gateway...but I can't get the 3548 to trunk with the 2950 (10.5.0.3)? I don't know if looking at the sh int * switchport is telling me something or not. On the 3548, I see the following "Access Mode VLAN: 0 ((Inactive))", and on the 2950 I see this, "Access Mode VLAN: 1 (default)." I keep getting incomplete arp entries, and can't ping across. I have tried to the "switchport nonegotiate" on the 2950 as well, and this didn't change anything. I have changed both switches native vlan from 1 to 1000, and have moved the mgnt vlan from 1 and 7 as well.Then I tried to trunk two 2950s...same config on both and no luck, until I enable the "switchport nonegotiate" command on both switch ports. Any ideas of what I may be doing wrong.
