The following example monitors and displays information about port extender interface 255/0/0. Dell(conf)#monitor session 1 source peGigE 255/0/0 destination TenGigabitEthernet 0/23 direction both Dell(conf-mon-sess-0)# Dell(conf-mon-sess-0)#do show monitor session 1 SessID Source Destination Dir Mode Source IP Dest IP DSCP TTL Mirrors-Drop? 1 PeGi 255/0/0 Te 0/23 both Port N/A N/A N/A No NOTE: Source as VLAN is achieved via Flow based mirroring. In the following example, the host and server are exchanging traffic which passes through the uplink interface 1/1. Port 1/1 is the monitored port and port 1/42 is the destination port, which is configured to only monitor traffic received on tengigabitethernet 1/1 (host-originated traffic). Figure 106. Port Monitoring Example Remote Port Mirroring Local port monitoring allows you to monitor traffic from one or more source ports by directing it to a destination port on the same switch/router. Remote port mirroring allows you to monitor Layer 2 and Layer 3 ingress and/or egress traffic on multiple source ports on different switches and forward the mirrored traffic to multiple destination ports on different switches. Remote port mirroring helps network administrators monitor and analyze traffic to troubleshoot network problems in a time-saving and efficient way. 798 Port Monitoring
