We have a case where with C9200 switches we configured two REP edge no-Neighbour ports to connect a device that does not support REP as documented in figure 54 at this link
interface GigabitEthernet1/0/2
description Link FROM CPU 2 ETH2
switchport trunk native vlan 120
switchport trunk allowed vlan 120,255
switchport mode trunk
rep segment 2 edge no-neighbor primary
spanning-tree portfast trunk
!
interface GigabitEthernet1/0/3
description Link FROM CPU 2 ETH3
switchport trunk native vlan 120
switchport trunk allowed vlan 120,255
switchport mode trunk
rep segment 2 edge no-neighbor preferred
spanning-tree portfast trunk
!
We find ourselves in the case where we have to replace the C9200 model with the IE4010 series and going to configure these two ports in the same way we receive this error:
Error: Segment id 2 already has one edge no-neighbor port. Cannot configure another edge no-neighbor port.
We cannot understand why it is not possible to configure two no-neighbour edge ports, even in the IE4010 documentation the same case is stated.
In both documentation, however, this sentence is also written:
If two ports on a switch belong to the same segment, they must be both edge ports, both regular segment ports, or one regular port and one edge no-neighbor port. An edge port and regular segment port on a switch cannot belong to the same segment.
If I am interpreting correctly, it is no longer possible even though the case in the documentation is there? What can we do?
Thank you
