New Catalyst Express 520G switch is to be connected to 6509 using a trunk. The existing network consists of 3560 switches as access and 6500 as core. The existing Voice VLAN ID is 1000 and 1001, where VLAN 1000 is for Voice servers and 1001 is for IP Phones. When configuring VLAN in the CE 520G switch the option says "VLAN ID: [2-1000]". How can I extend the VLAN ID range on the CE switch?
