Connectivity Guide

Reserved L2 VLAN
• MAC address learning in the reserved VLAN is automatically disabled.
• There is no restriction on the VLAN IDs used for the reserved remote monitoring VLAN. Valid VLAN IDs are from 2 to 4093. The default
VLAN ID is not supported.
• In monitored trac, if the device has a L3 VLAN congured, packets that have the same destination MAC address as an intermediate
or destination device in the path the reserved VLAN uses to transport the mirrored trac are dropped by the device that receives the
trac .
Source session
• Congure physical ports and port-channels as sources in remote port monitoring and use them in the same source session. You can use
both L2, congured with the switchport command, and L3 ports as source ports. Optionally, congure one or more source VLANs
to congure the VLAN trac to be monitored on source ports.
• Use the default VLAN and native VLANs as a source VLAN.
• You cannot congure the dedicated VLAN used to transport mirrored trac as a source VLAN.
Restrictions
• When you use a source VLAN, enable ow-based monitoring using the flow-based enable command.
• In a source VLAN, only received (rx) trac is monitored.
• In S5148F-ON, only received (rx) trac is monitored.
• You cannot congure a source port-channel or source VLAN in a source session if the port-channel or VLAN has a member port
congured as a destination port in a remote port monitoring session.
• You cannot use a destination port for remote port monitoring as a source port, including the session the port functions as the
destination port.
• The reserved VLAN used to transport mirrored trac must be a L2 VLAN.; L3 VLANs are not supported.
Congure remote port monitoring
Remote port monitoring requires a source interface, monitored ports on dierent source network devices, and a reserved tagged VLAN for
transporting mirrored trac congured on the source, intermediate, and destination devices.
1 Create a remote monitoring session in CONFIGURATION mode.
monitor session session-id type rpm-source
2 Enter the source to monitor trac in MONITOR-SESSION mode.
source interface interface-range direction
3 Enter the destination to send the trac to in MONITOR-SESSION mode.
destination remote-vlan vlan-id
4 Enable the monitoring interface in MONITOR-SESSION mode.
