I am trying to configure a GRE tunnel between a CE6850 & a Cisco Catalyst 6509 switch. However the tunnel will not come up on the 6850, although i have layer 3 connectivity between the source & destination ip address's. There are No Firewalls in between Has anyone done this before?

We have replaced 2 x B200 M3 servers in a chassis, with a single B420 M3 server. Keep getting an issue that both the adaptor host interface & the virtual interface are down. Created a clone of a working service profile on another B420 server in the same environment. Can anybody tell me why?  ... View more

How can i tell if a service profile is configured for a windows server?   thanks Colin ... View more

Have an issue, where Ospf will not come up between a 2921 running 15.2(4)M4 and a 3750G running 12.2(35)SE5. Ospf is running between physical interfaces. Ospf running between the 2921 and a 6513 with no issue. Ospf running between the 3750 and other switches no issue. debug ip ospf hello, shows hello's bein sent from the 2921 to the 3750, but none from the 3750. Unable to run debugs on the 3750 as it is in production. able to ping between the devices and tried configuring different type of Ospf network types. Has anyone seen this issue? Thanks Colin ...

I am having a problem browsing UCSPE version 2.1.3aPE1 from another VM on my laptop. I can ping, but unable to browse. Console displays "error while running vm security tool please perform re-stamping. I have logged into the console & already tried a factory reset.                   I can access an older version of UCSPE 1.3(1c), so i am wondering if the issue is the version of my vmware workstation (7.1.6). I think i read somewhere about an incompatability. Also, are there any labs around for actually using UCPSE? Regards Colin ... View more
