I need some help with the configs below. Seems there is some serious
latency going from one Vlan to the next. I took out the 2620 to try and
just use the 2948G L3 but not much improvement. Not sure if need the ip
route statements of the 2948G L3 or whether I need the more BVIs. Not
entirely sure exactly what the config is doing. There are other 2948Gs
not L3s hanging off the L3 using trunk ports. I didn't include their
configs. For example: Vlan 30 is out on a 2948G hanging of the L3 and the
L3 has a couple of Vlan 30 ports for users also. Seems this is causing
serious latency issues. Thanks. Cisco 2620 Version 12.0 ! int fa0/0
