NE80E version: VRP5.30-31002S.03
Failure symptoms: When NE80E is configured with port mirror, only the inbound packets can be captured.
1. To check the packets passing through the optical interface, configure port mirror at NE80E; capture packets at the electrical interface of slot 10, and the configurations are as follows:
observe-port 1 interface GigabitEthernet10/0/7
ip binding vpn-instance ngn_ceshi
ip address 192.168.254.1 255.255.255.0
port-mirroring to observe-port 1 inbound
port-mirroring to observe-port 1 outbound
The configuration is correct.
2. According to the packets captured, there are only ingress packets, but not egress packets.
3. NE80E at the version only supports the port mirror for inbound interface, not for outbound interface.
1. The configuration is problematic.
2. The version is problematic.
