Hi guys ,
i've a problem with tagged vlan with my SRW224G4P.
I,ve got following scenario:
one cisco 2801-CCME/k9 router
one cisco small business SRW224G4P layer 2 managed switch
ten cisco IP phone 7940 and 7931
ten personal computer
I need to use the embedded switch on the phone to connect computer . I need to
have 2 separated vlan for data and voice traffic.
I configured srw224g4p first 12 ports as follows
interface ethernet 1/x
switchport allowed vlan add 199 untagged
switchport native vlan 199
switchport allowed vlan remove 1
switchport mode hybrid
switchport allowed vlan add 150 tagged
spanning-tree cost 100000
where vlan 199 is for data and vlan 150 is for voice .
I set following dhcp pool on 2801
ip dhcp pool phones
network 192.168.150.0 255.255.255.0
option 150 ip 192.168.150.1
ip dhcp pool PC
network 192.168.199.0 255.255.255.0
and configured router on a stick as follows
description CME interface
encapsulation dot1Q 150
ip address 192.168.150.1 255.255.255.0
encapsulation dot1Q 199
ip address 192.168.199.1 255.255.255.0
My problem is that phones connected to the switch ports doesn't recognize tagged
traffic and doesn't take ip of the corrected dhcp pool of 150 vlan.
With a cisco 2960 poe switch i configured switchport voice vlan 150 and
switchport access vlan 199 and all is fine but this small business switch don't
handle switchport voice attribute and i can't separate voice and data vlan .
Someone have idea how to avoid this problem?
Need some help , please.
