Hi there!
I recently added a second CRS317-1G-16S+ to my setup and configured the two switches to do MLAG.
I dedicated two Interfaces to ICCP and put them in a LACP-Trunk: “LACP-ICCP”
Some hosts are connected to Core1, some to Core2: NOT using MLAG or LACP.
My router, CCR2004, is attached to both via MLAG. Interface Name on Core1 and Core2: “sfp-sfpplus15-MLAG-CCR-PRI”
My Access layer Switch is attached via MLAG as well. Interface Name on Core1 and Core2: “sfp-sfpplus12-MLAG-Core2Access”
I have another CCR2004 sitting in the Shelf waiting for me to find some time to configure VRRP between both CCRs: “sfp-sfpplus16-MLAG-CCR-Sec”
but since the device is currently off and not connected they are disabled.
Most things work as expected, but i just saw that my DCs are not replicating since yesterday.
RPC errors…
They are on the same vlan and subnet.
ICMP is fine.
I can iperf between the nodes with speeds >9gbit/s.
No Firewall in between.
I find i quiet hard to identify a RPC Problem since everything except that “seems” to be working.
Nevertheless, i thought i`d post my switch configs and ask the community for help:
Can you spot obvious configuration errors on the switches?
Any improvements you would recommend?
