Hello,

 

 

To have better knowledge/understanding about MCCIP,  i try to configure one in my lab.

 

I use AFF A220 HA pair and a Lenovo DM5000H HA pair + BES53248 switchs => It is only for test.

 

  • All node/ chassis put in mccip
  • intercluster lif are ok
  • cluster peering ok

Did you check your cluster switch ports ( BES53248 switches) configuration? Not seeing any outputs from them.

hello:

  The MetroCluster IP HA within the cluster has an unconnected ISL. Check and correct the cabling and/or configuration of the MetroCluster IP interconnect ports. The following article is hoped to be of assistance to you.

Best regards.

Hello,

 

Than you both for your reply.

 

I agree, pretty sure it is related to switch config/cabling.

As i use only 2 BES53248 i try to modify the config after applying the RCF file.

Cluster port for ha pair and MCCIP interconnect use port e0a and e0b /e0a-10 e0b-20

 

On which port of the switch do i need to connect them?
