One-sided link down Cisco - HP GbE2 Switch
I'm running into some problems connecting my GbE2 Switch to a Cisco 6506 2-system VSS setup.
The Blade side link is UP, while the Cisco side link remains 'notconnect'.
It's a change to a tagged setup with etherchannel link.
I've added the configuration of Switch A and some Cisco output (with LACP etherchannel and last summary normal etherchannel).
No matter which setup I try the link remains not connected.
What I've tried.
- reconfig from normal etherchannel (mode on) to LACP (mode active) on the cisco
- changed hardware: SFPs/cabling/fysical connection from switch 1 to switch 2 of the VSS system/changed uplink from sw A to sw B
- tried single link uplink, no etherchannel
- re-entered 'no shutdown' on the cisco interfaces
But no help there, the cisco side stayed notconnect.
Any help is appreciated!

Re: One-sided link down Cisco - HP GbE2 Switch
what happens if you only connect one port of the configured channel?
what messages occur in the log of the switches?

Re: One-sided link down Cisco - HP GbE2 Switch
So 1 fiber from 1 bladeswitch to 1 coreswitch:
1/2/10 OR 2/2/10.
Both react the same way.
I have an small update though.
I configured port 21, which was in use before the reconfig in an uplink to an other enclosure (so that port worked) as a part of the trunk 2 as well.
Connected that one to port 1/2/10 of a cisco core: not connected
removed that port from the port-channel on the cisco, et voila: trunked and working:
blade trunk -> cisco core no-etherchannel
tried the same cable to the other port/core 2/2/10: not connected.
reconnected that same cable to the 1ste core again to get it working again: notconnected!
On all situations the bladeswitch notified as link going up on physical connection of the cable.
And it hasn't worked since.

Re: One-sided link down Cisco - HP GbE2 Switch
I will try that after the weekend.
Of course I did do an apply to make the changes active.
Thank you for thinking with me!

Re: One-sided link down Cisco - HP GbE2 Switch
I miss step 3 in your config.
3. On both Cisco 6509 switches, enable 802.1Q tagging (VLAN trunking) on all ports connected to both GbE2 Interconnect Switches per the command:
6509# set trunk

Re: One-sided link down Cisco - HP GbE2 Switch
the exact frase cannot be used as the document refers to CatOS config and ours is IOS based config.
