Issue Description
Q:
The situation of S9300 switch supporting far distance mirroring
Handling Process
A:
S9300 switch supports far distance mirroring, which divided to layer 2 and layer 3 far distance mirroring.
Layer 2 far distance mirroring was supported by all devices, Layer 3 far distance mirroring was supported by enhance type board.
Configure Layer 3 far distance mirroring on standard board, it will warn the following failure:
[S9300-GigabitEthernet1/0/1]port-mirroring to observe-port 1 both
Error: This board cannot support ERSPAN.
The packet will be encapsulated to GRE packets after S9300 configured far distance mirroring, it can get GRE packet head by packet getting tools, but the data encapsulated in GRE cannot be identified, it need special software to identify.
