Hello,
we use RouterOS 7.9 with CRS354-48P-4S+2Q+.
We would like to use DHCP option 82 to allow access via the Circuit-id, now the problem is the Circuit-id is not predictable.
It is the same bridge with DHCP snooping and the Option82 activated, same bridge port configuration etc.. but even if the differ, in my opinion the Circuit-id should be predictable.
In one case it adds 13 in the other case it adds 14.
ether9 + 13 ( in case one ether9 + 13 = 22:10)
DHCP options:
[82] Relay agent information: len = 35
[1] Circuit-id: SWITCH02 eth 0/22:10
[2] Remote-id: ether9
In the other case the Circuit-id is ether43 + 14 = 57)
[82] Relay agent information: len = 36
[1] Circuit-id: SWITCH02 eth 0/57:10
[2] Remote-id: ether43
I've downgrade to 7.7 but all the version show this behavior, I see in wireshark the CRS354 send the "wrong" Circuit-id:.
Any ideas?
Thank you
Seb
