voice port config
have a 3com 7750 connected to a alcatel pbx. need correct config for the uplink port. current config is as follows: interface GigabitEthernet2/0/1
stp edged-port enable
port link-type hybrid
port hybrid vlan 2 tagged
port hybrid vlan 1 untagged
broadcast-suppression pps 3000
my edge switch has following config:
interface Ethernet1/0/1
poe enable
stp edged-port enable
port link-type hybrid
port hybrid vlan 2 tagged
port hybrid vlan 23 untagged
undo port hybrid vlan 1
broadcast-suppression pps 3000
packet-filter inbound link-group 4999 rule 0
the problem is i cannot ping the pbx from my edge switch whether i have configured my laptop for the data vlan or the voice vlan

Re: voice port config
If VLAN 1 is disabled on E1/0/1, but the PVID is still VLAN 1, E1/0/1 will not be able to receive any untagged packets. In addition, VLAN 23 is not configured on interface GigabitEthernet2/0/1.
Is your configuration complete?
Suppose your IP phone sends tagged traffic, and VLAN 2 is your data VLAN. (to my knowledge, if your IP phone sends untagged traffic, PVID must be the same as the voice VLAN ID.)
Change as follows and try again:
interface Ethernet1/0/1
poe enable
stp edged-port enable
port link-type hybrid
port hybrid vlan 2 untagged
port hybrid vlan 23 tagged
port hybrid pvid vlan 2
undo port hybrid vlan 1
broadcast-suppression pps 3000
packet-filter inbound link-group 4999 rule 0

Re: voice port config
vlan 23 is my data vlan and to my knowlege pvid is the data vlan as it is the default vlan. my problem is i have several data vlans including the vlan 23 but the data vlan on my core switch is vlan 1, now my pbx is connected to the core on port 1. if i remove the pvid 23 on my edge switch i can ping the pbx eg.
undo port hybrid pvid vlan 23
i can then ping the pbx, now it seems to me like intervlan routing is not working but do not know how to correct this.
correct scenario is i should be able to ping the pbx while in the vlan 23

Re: voice port config
i have also configured vlan interface 23, 1 and 2 for routing and aslo enabled rip. as i said if i disable pvid 23 and enable vlan 1 on port e1/0/1, i get replies from the pbx.

Re: voice port config
Which port is the uplink port of 3com 4500 to 3com 7750? Which port is the downlink port of 3com 7750 to 3Com 4500?
You have a VLAN-23 interface on 7750, but I didn't see any port in the VLAN.
