Hi, I have one ASA 5512-X and 5515-X Firewall at my data center. One of them is running as production box and the second one is available offline, this is fully configured to act as redundant firewall if the primary fails. We are currently running at risk having this manual switch over as the fail over plan. Is it possible to configure an active/active or active/standby failover using these two different model ASA firewalls.

I have been using my API User ID to login to Cisco Mediasense administration page. Suddenly it stopped working for me, I get invalid user ID or password error when I try to login now. The API user ID is synced with CUCM hence I suspect some issue between CUCM and Mediasense. I dont have any other credentials to login to the administration page, except the SSH credentials. Any idea what could be the reason for this ?

Hi, We have a Multihomed(2-ISP on 1-Router) BGP connectivity for ISP redundancy, through this link we are advertising our own IP prefix. The link failover works perfectly fine, it happens if either of the local loop for the ISP physically goes down or if the remote peer(neighbor router) is not reachable. The existing BGP configuration is not helping us much to address the intermittent packet loss issues that occurs with some of our critical remote destinations. I am not sure how we can fix this issue on the gateway router. I am actually trying with IP SLA configurations to see if we can address this issue. Let me know if there is a better way to address such issues on border router.

We have tried the STP option but having issues at ISP side and therefore the link was fluctuating. We are now concentrating on port channel and seeing the possibility of implementing it.I understand from all those folks posted here, it is surely an option that would help us to achieve both load balancing as well as failover.

Yusuf, We are using fiber connectivity only. The distance between the two sites is more than 5 Kms and we are using the shared ring loop network of two ISP's using the Q-in-Q mechanism to reach the other site.

Yusuf, The topology is simple. We are planning to have a point to point connectivity to the datacenter from our office. For redundancy purpose we are looking for a failover scenario by using two point to point links.

Sharon, I am new to HSRP on switch, have done with the routers. But again not sure with L2. Does HSRP work on L2 switch ? Anyway at this moment we are not looking for switch redundancy, we will just accomplish the link redundancy.

Alain, Thanks for your query. Thats not a problem, we will be connecting the links to the same L2 device at both side.

Jason, Thanks for the detailed explanation. Actually we had planned for either STP or Port channel as options to achieve the failover connectivity at L2 layer. The initial impression was that the port channel option might not be supported in a scenario where two different ISP's are enagaged. Now we are in a situation where the STP option is not applicable. Do you see any issue in achieving the port channel when we have two separate ISP ? Will the port channel works in case if ISP using Q-in-Q tagging at their side of the link. ?

We have 2 point to point links from 2 different ISP's for the purpose of connecting to our data center from our office. We would like to configure a failover scenario using these two P2P links. I have been trying with the sTP method but for some reason we could not succeed in this, could be because of the distance. Please help me to implement a failover P2P conectivity usign this two links.

You are right Rick, it is an unusual scenario. Anyway finally we found it was the DNS that was causing the issue. Thanks a lot for your assistance.

In one of our remote office we have a small LAN with a 3750PoE core and a 3560 client switch. Suddenly the core switch got hanged, the network came back after we did a hard restart of the core switch. After this breakdown, the machines conncted to the core switch is unable to connect to internet addresses, surprisingly all the machines connected to the client switch can still access internet. The core switch has only one default route which is pointing to the firewall. All the LAN addresses are reachable locally as well as through the VPN. Since the internet works from the client switch and also the VPN is working perfectly fine, therefore we cannot doubt the firewall. Please let me know if this is an issue with the switch IOS or any configuration.

You are right. do you think the #sh fabric utilization command helps to monitor the traffic on the line card ? Could you please help me with few commands that could help in similar cases related to line cards ? Is there a way to monitor the line card for real time values. ? If i get a similar case next time i must ensure that i am prepared to run few diagnosis.
