SRX redundant Ethernet interface does not come up.

  • 1.  SRX redundant Ethernet interface does not come up.

    Posted 09-20-2018 12:20

    I configured a redundant Ethernet interface in an SRX1500 cluster using a 10 Gbps interface on both devices.  I need to change this reth to use 1 Gbps interfaces; thus, I changed the configuration to remove the 10 Gbps interfaces from the reth and from interface  monitoring; then I added the 1 Gbps interfaces to the reth.  However, the reth does not come up, but the constituent physical interfaces do come up. 

     

    root@SRX1500-cluster> show interfaces reth0

    Physical interface: reth0 , Enabled, Physical link is Down

     

    As a test, I configured a new reth with the two 1 Gbps interfaces and it worked.

     

    It seems that the first reth that I configured has a 'memory' of the two 10 Gbps physical interfaces.

     

    I see the entries below in the message file.

     

    Sep 20 18:28:53 SRX1500-cluster SRX1500-cluster COSMAN: policy update failed
    Sep 20 18:28:53 SRX1500-cluster /kernel: kernel did not add link reth0, link speeds differ 1000000000 10000000000
    Sep 20 18:28:53 SRX1500-cluster/kernel: bundle reth0.1296: link ge-0/0/14 not added due to speed mismatch

     

    May I ask if anyone has seen this before, please?

    Can you please provide the following information.

     

    * running Junos version

    * chassis cluster configuration

    * output from 'show chassis cluster interfaces' ?

    * output from ' show configuration |display set |match "redundant-parent reth" '

     

    This will make it a lot easier to help. Thanks.

    Thank you for your support.  I returned to the original configuration using the 10 Gbps interfaces for reth0 and configured a new reth, reth4, that uses the 1 Gbps interfaces.  I plan to rewrite the configuration file from scratch to use the reth4 interface where I use the reth0 interface now.

    Ok. Remember that you can quickly move all configuration to reth4 by doing a simple "replace pattern reth0 with reth4" in configure mode and then just revert to reth0 on the 10G port.

    Thank you for your support.  The 'replace pattern' command is most useful.

    FYI.

     

    I tried the 'replace pattern' command; the result is below.

     

    root@SRX1500-cluster# replace pattern reth0 with reth4
    error: target statement 'reth4' already exists
    [edit interfaces]
    'reth0'
    could not rename to 'reth4'

     

    Thus, I ran 'replace patterh reth0 with reth10' and then configured the 1 Gbps links to have reth10 as their redundant parent.  Lastly, I changed the redundant parent of the 10 Gbps to be reth0, as you recommended.
