i have a cisco 4500 switch......and the 4th line card on it has all the IP phones connected to it.there r primarily 2 VLANs....109 is for data and 145 is for voice.now i have an other switch(linksys).....which i want to use it for IP phones. I need to uplink this switch to this 4500 switch.so what should be the config on this linksys and cisco uplink port...

Hello Sham,
the Vlan(s) used for VOIP phones need to be carried over the inter-switch link.
if it is only one you could think of an access link.
Otherwise a L2 trunk is needed.
In that case I would suggest to specify the allowed vlans
int gx/y
switchport
switchport enc dot1q
switchport mode trunk
switchport trunk allowed vlan 1,145
example the list is made of vlans separated by ',' without spaces in the middle. Ranges are allowed using the '-' sign
You need to define the vlans on linksys if it is configurable.
If it is a plug and play device you probably should configure the link as an access link in vlan 145
Hope to help
