7800 Router Configuration Challenges

  • 1.  7800 Router Configuration Challenges

    Posted 01-30-2013 01:07 PM

    I'm configuring two 7800 routers for storage replication across a network for DR. I've followed the instructions to create the EX ports, set the fabric IDs for the EX ports, set unique domain IDs for all participating switches, configured the GE0 ports and created the circuit. I'm able to ping from both ends and it seems everything is setup correctly. The problem I have is the FCIP tunnel is bouncing up and down. I'm not able to see the fabric information for the peer switch. Here's some information about the configuration from one router. Any suggestions on why it's bouncing?

    Hi harold,

    you told you are able to ping both ends. Which cli exactly are you using ?

    Could you provide portshow ipif all on both routers ?

    I would not configure FCIP interface's IP in the same subnet of LAN interface's IP, I think it may be confusing.

    Kind regards

    Turn off EX_Port back to a standard port and let the 7800 do its thing and your fabrics will merge, I think this should solve your issue

    You don't need to turn off routing to troubleshoot this type of problem. The 'flapping' GbE port could be due to several factors. One of those is marginal physical layer or an invalid commit rate. Please refer to the FCIP Admin guide for suggestions regarding commit rate configuration. There are several commands to display the port level physical layer errors. Make sure they are clean. Also, when you performed the ping command were there any lost packets?

    Thanks you all for your suggestions. I changed the IP address and subnet on the management interface as I thought that was the problem. I am still have problems though. Here are the latest configurations:

    Posted 02-06-2013 09:12 AM

    Could you provide (only) portshow fciptunnel all and portshow fcipcircuit all on both sides ?

    Did you try first without enabling Fastwrite ? BTW if you are not sure you need Fastwrite and don't know what it's done for, don't use it.

    Kind regards,

    Harold,

    What version of FOS are you using? Additionally, has your array manufacturer recommended the Fast Write configuration? What are the messages displaying in the error log when the ports are 'flapping'? Lastly - do you have a case open with your support provider TAC?
