What? you want move ALL workstations of VLAN 1 as this is amanagment VLAN
and only switch/routers should use this. For your info, I have assigned
quite a lot of PC to VLAN 1 ports and I used VLAN 1 ports to connect to the
WAN via routers too. Will it slow down the network?? why??

>>I need to solve a network slowness problem. First, let me tell you about

>>Besides, both 5500 are connected to the company WAN via two 1700 routers.

>>
>>MTU 1500 bytes, BW 256 Kbit, DLY 20000 usec

>>I heard from my friend that Cisco router is poor in handling citrix and

>>RSMs. Could the difference in routing protocol slow down the network?
