Procurve 5406zl

[Alex Casanova]

I am currently interconnecting one Dell PowerConnect 5324 to an HP 5406zl Switch.

In the Dell 5324 the G23 port is in Trunk mode

In the 5406zl have 3 VLAN (VoIP, Servers, Default VLAN). I use the port A1 for Interconnect the 2 switches.

The 5406zl switch have the 10.0.0.96/16 ip address and 10.0.1.1 for Gateway.

I can´t ping from LAN (10.0.0.0/16) to a telephone in (10.1.0.0/255.128.0.0) but i can ping from switch to 10.0.0.75 or 10.0.1.1 (gateway) correctly. From VoIP VLAN i can ping the 10.1.0.1 gateway but i can´t ping other ip address outside the 5406zl switch.

This is the running-config

Hi Alex,
>>>
vlan 1
ip address dhcp-bootp
<<<

So on vlan-1 the switch has a dhcp-assigned addrss, not fixed.
Therefore hosts in vlan1 cannot be configured with this switch as default gateway!

this is the followed path
host -> vlan1 -> !!!vlan1-gateway!!! -> vlan3 -> phone -> -> vlan1 -> host

you better change the vlan1 address to a fixed address and configure this address as default gateway in the dhcp scope.

Thanks a lot for the answer. I try with a new configuration in my switch following your instructions.

Now the problem is: when i submit the config to the switch i can ping from VLAN VoIP any computer in other VLAN, but a few minutes later I start to loss pings, and i can´t ping from VoIP to any computer in Default_VLAN.

There is the config:

ip routing
vlan 1
name "DEFAULT_VLAN"
untagged A1,A3-A24
ip address 10.0.1.18 255.255.0.0
tagged A2
no untagged B1-B24
exit
vlan 2
name "servidores"
untagged B1-B24
tagged A1
no ip address
exit
vlan 3
name "VoIP"
untagged A2
ip helper-address 10.0.1.20
ip address 10.1.0.1 255.255.128.0
tagged A1
exit
qos tcp-port ipv4 5060 priority 7
qos udp-port ipv4 5060 priority 7
qos udp-port ipv4 range 10000 20000 priority 7
router rip
exit
snmp-server community "public" unrestricted
vlan 3
ip rip 10.1.0.1
exit

vlan 1
ip address 10.0.1.18 255.255.0.0
exit
vlan 2
vlan 3
ip helper-address 10.0.1.20
exit
router rip

I think this comes down to RIP version 1.
RIPv1 is not VLSM aware.
So it thinks all 10.x.x.x/8 adresses are on the same network segment.

Do you have any other routers in your network?
If not disable rip as it is only usefull when routing must dynamically change.
If so try changeing to RIPv2.

Thanks a lot for your answer.
With the last config all are ok, but a few minutes later I lost de connectivity with the VLAN VoIP from outside.

We don´t have any router outside, i only have de 5406zl switch and the GW to go outside the LAN across the Internet line.

Finally i will try to open a study case in HP, i think this issue its very strange.

Thanks a lot for your time and your answers

>>> We don´t have any router outside, i only have de 5406zl switch and the GW to go outside the LAN across the Internet line. <<<

So you can remove the RIP configuration as there is no other RIP router to communicate with.


>>> and the GW to go outside the LAN across the Internet line <<<
Check this router has the correct network mask configured AND is configured for VLSM.

RIP configuration removed.

This is the new configuration:

ProCurve Switch 5406zl(vlan-1)# sh run

More information. I enabled the STP, and when I check the log: I see that the port A2 and A2 are blocked by STP.

Log:

00435 ports: port A2 is Blocked by STP
00435 ports: port A1 is Blocked by STP
00839 stp: CST Root changed from 32768:0026f1-0ce400 to 32768:0015c5-2eab6b
