F5/Cisco catalyst configuration question

2009-08-19 Thread Scott Spencer 
Trying to link an F5 Local Traffic Manager with a Cisco Catalyst 6500 , have
matched ports (speed,duplex ect..) but no link light at all on the F5. Does
link with a Cisco 2950 switch in between but I need a direct connection with
the 6500.
 
Any suggestions what to try?

Scott,

We've had issues in the past with IOS 6500's auto-negotiating uplink ports with 
an LTM into ISL Trunk mode. This only occurred when we had the port on the LTM 
configured as a tagged interface. It was easily solved by forcing the port on 
the 6500 into dot1q encapsulation. I'm not sure this necessarily explains why 
you aren't seeing a link light on the LTM though. I can't remember what the 
interface status was on both sides. This does correlate to why it's working on 
the 2950's as they don't support ISL and would likely negotiate into dot1q.

What model BIG-IP?
On some models I have had to set the BIG-IP's or the 6500 (can't remember
which) to specified speed/duplex and the other side to auto.

I believe it was auto on the BIG-IP and fixed on the 6500.

Setting both sides the same did not work.

We have some F5 3400s.  No issues with getting link up, but have had
issues with etherchannels.  Our F5 admin wanted to run LACP, but we have
had some issues. 

3400 to Cat3750 seems to work okay, doesn't always like both ends
'active' as per Cisco recommended lacp settings.

3400 to Cat3750E we couldn't initially get LACP up in any case, but it
maybe have been a flaky switch (had stack port issues), haven't tried
again since the replacement.

Seems to be fine with raw etherchannel (channel-group xx mode on).

Anyone have "smarter" etherchannels running F5-to-Catalysts ?

Jeff

Yes, I'm running LACP between SUP-720 6500s and BIG-IP 6900 boxes on
the SFP interfaces.  The key was to disable ethernet flow control on
the BIG-IP side.  They enable it by default and it really confuses the
Cisco side.

After disabling flow control on the BIG-IP's physical interfaces, LACP
came up just fine.
