Netgear M5300-28G-POE+ (GSM7228PSv1h2) - 12-Port Managed Gigabit Switch Softwarehandbuch

This command enables debug traces for checkpointing control messages that are exchanged 
between MLAG devices on the peer link. For errors, only the errors in the communication are 
traced. For messages, the control message contents that are exchanged can be traced. Both 
transmitted and received control messages contents can be traced.

This command enables debug traces for the dual control plane detection protocol. Traces are 
seen when the DCPDP transmits or receives detection packets to or from the peer VPC 
switch.

To display the debug trace, enable the 

 command.

Port mirroring, which is also known as port monitoring, selects network traffic that you can 
analyze with a network analyzer, such as a SwitchProbe device or other Remote Monitoring 
(RMON) probe.

This command configures a probe port and a monitored port for monitor session (port 
monitoring). Use the source interface unit/slot/port parameter to specify the 
interface to monitor. Use rx to monitor only ingress packets or use tx to monitor only egress 
packets. If you do not specify an rx or tx option, the destination port monitors both ingress 
and egress packets. 

A VLAN can be configured as the source to a session (all member ports of that VLAN are 

monitored). Remote port mirroring is configured by adding the RSPAN VLAN ID. At the 
source switch, the destination is configured as the RSPAN VLAN and at the destination 
switch, the source is configured as the RSPAN VLAN. 

The source and destination cannot be configured as remote on the 
same device. 

The reflector-port is configured at the source switch. The reflector-port forwards the mirrored 
traffic towards the destination switch.
