I didn't know whether to place this in here or in the IP telephony section. Anyway, we recently had some lightning damage a switch. It's in a little used building (four computers, two phones) so instead of replacing it with the same switch (Catalyst 29xx series), I did a little research and found the SF-300-24 should be able to do the same thing for much cheaper.
Anyway, I was a little surprised when I got the switch and couldn't do much from the command line. Here's a snippet of my config from the old router...
interface FastEthernet 0/1
switchport access vlan 2
switchport trunk encapsulation dot1q
switchport mode trunk
switchport voice vlan 2
(other ports same)
ip address 18.104.22.168 255.255.252.0
no ip directed-broadcast
no ip-route cache
Anyway, I am trying to get the new switch to work and I'm having trouble getting the ip phones to work. I've given all ports access to VLAN 1 (default) and VLAN 2 which is the vlan our core router uses for the ip phone network. Using a Cisco 7940 phone (along with Cisco Unified CM version 22.214.171.12401-1). When I plug a computer into the new switch (which I've programmed to use the same ip as the old switch), I'm able to browse internet, access network, etc. However, when I plug a phone in, it constantly says "Configuring IP" - it's not grabbing any of the correct settings (ip address is in the 100.234.8.x and not in the 100.234.5.x that phones should be getting). TFTP server is blank (should be 126.96.36.199) and default router shows the gateway and not what other phones are grabbing (188.8.131.52).
A consumer router may support a virtual private network (VPN) connection, but that's a far cry from the network and security capabilities that a business-class router can provide. All it takes is some IT talent and know-how to set one up. You're hear...
