WOL edge 2650's

Hi I hope someone can give me some pointers on this.

I have core 3750's cisco switches and 2950 cisco edge. We are now integrating 2650's as our edge instead of the ciscos.

My WOL works on the ciscos, but not on the hp's. Is there some sort of configuration i must do on the hp 2650's to set this up (pass through the magic packet)?

Config of 2650 is below:

; J4900B Configuration Editor; Created on release #H.10.38

hostname "Spare"
ip default-gateway 10.12.7.253
no timesync
snmp-server community "public" Unrestricted
vlan 1
name "DEFAULT_VLAN"
untagged 25-26
ip address 10.12.7.140 255.255.248.0
no untagged 1-24
exit
vlan 18
name "F_Centre"
untagged 5-22
tagged 25-26
exit
vlan 9
name "voice"
untagged 23-24
tagged 25-26
exit
vlan 40
name "Wireless"
untagged 1-4
tagged 25-26
exit
password manager
password operator

Thanks in advance

Re: WOL edge 2650's

Hi

Wake on LAN is a directed broadcast kind of traffic that the 2600 series doesn't forward by default.

A directed broadcast is an IP broadcast to all devices within a single directly attached
network or sub-net.
A net-directed broadcast goes to all devices on a given network.
A sub-net-directed broadcast goes to all devices within a given sub-net.

Forwarding for all types of IP directed broadcasts is disabled by default.

You can enable forwarding for all types if needed.
You cannot enable forwarding for specific broadcast types.
To enable forwarding of IP directed broadcasts, enter the following CLI
command:

HPswitch(config)# ip directed-broadcast

Check this, page 12:

Good Luck !!!

Re: WOL edge 2650's

As far as I know, 'ip directed-broadcast' should only have an influence if the 2600 is performing routing.

Re: WOL edge 2650's

It's usually at this stage that I'd start up wireshark to understand exactly where the WOL packet was getting stopped. I'd start by monitoring the 2600's uplink port.

Otherwise if you could attach the config of the core routers and that of the 2950's, I'm sure someone here could at least verify that the config that's running the 2600's does match the 3750's. I assume it is correct since it sounds like everything else is working.
