VLAN Routing issue - ProCurve 2848

[bullyman99]

Howdy All:

I need your help.  I have VLANS that are intermittently communicating with each other, that is, sometimes I can ping from VLAN1 (Default VLAN - the Company LAN) to VLAN20 (Voice - Phone System Network) or vice versa.  But sometimes I get no replies as well.

Our 2848 configuration is setup as the following:

- VLAN1 is set with IP address 10.10.0.240 and is our Default Gateway for our Internal LAN.

- VLAN20 is set with IP Address 10.20.0.240 and is the Default Gateway for our Phone System .

- IP Routing is 'ON'.

- Port 24 is attached to our Phone System and is untagged as VLAN 20.

- I can ping 10.10.0.240 and 10.20.0.240 from the Phone System Network without being intermittent.

- I can ping 10.20.0.240 and 10.10.0.240 from any LAN computer also with no intermittency.

- I can ping any Internal LAN IP or the Phone System network from the switch.

If any one has any ideas or sees where I have gone amiss, or needs further information, then your help will be much appreciated.

Thanks,

Carl
