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?
