Since upgrading to the ASA5585-X firewall running in multi-context mode we have had a number of questions around functionality.  We raised a case with Cisco TAC to find out why EIGRP peering is not supported between contexts.  This was their response:- Thank you for your patience on this case; the behavior you are seeing on the ASA is expected since inter-context exchange of multicast is not supported “Context Guidelines EIGRP instances cannot form adjacencies with each other across shared interfaces because inter-context exchange of multicast traffic is not supported.” https://www.cisco.com/c/en/us/td/docs/security/asa/asa96/configuration/general/asa-96-general-config/route-eigrp.html#ID-2179-0000001b As a workaround, you can configure static neighbors but it is supported only on point-to-point links. https://bst.cloudapps.cisco.com/bugsearch/bug/CSCuo76566/?reffering_site=dumpcr So due to inter-context exchange of multicast traffic not being supp...

Since migrating to an ASA5585-X running in multi context mode, we have been unable to use the clientless webvpn mode to push down the anyconnect software.  We opened a TAC case and got this response from Cisco. Thanks for the information provided. Unfortunately clientless webvpn access is not supported in multiple context mode, that is the reason why you get the “Internal server error” when trying to access the ASA using a browser. While using the ASA in multiple context mode you need to find an alternative way to distribute the Anyconnect software and profile to the remote users since you won’t be able to provide it directly from the ASA. The following enhancement request was opened to address this issue in future releases: ENH: Add Features in Remote Access VPN in Multi-Context Mode CSCuw19758 Description Symptom: This is an Enhancement Request Add support for below features in Remote Access VPN in Multi-Context Mode: 1. Username-from-certificate and pre...

In order to install a PVDM into the Cisco 2800 series simply follow the steps below. Firstly power down the router and remove the case by undoing the case screws. At the back of the router near the power supply you will notice the memory (DIMM Slots) and behind them the PVDM slots (which are white). If you look closely on the mother board you will notice that one is labeled PVDM0 and the other PVDM1. If you are only installing one PVDM then you will need to install it in the PVDM0 slot. The PVDM has a little notch cut out of it which means it will only fit into the slot one way.  Locate the PVDM into the slot at a slight angle and then tip pull it upright until the clips click into place and hold it in position. Put the case back onto the router and switch it on.  Once booted do a show inventory and you should now see the PVDM listed.

Whilst designing a new web farm network I needed to know how many SSL sessions our CSS was currently terminating in order to purchase the right SSL license for the Cisco ACE we were upgrading to. To determine the number of active SSL connections a CSS is using at that point in time use the command. show ssl flows The equivalent command on a Cisco ACE is... Show resource usage

First time I configured one of these it took me a while to figure out how to change the hostname. Its easy once you know the answer but it is not found in configuration mode. From enable mode you simply type the command prompt and then a name e.g.  CSS11500# prompt my-css-01 Simple huh!
