Configuring Mirroring
-
To create a named mirror instance, use the following
command:
create mirror mirror_name {to
[port
port | port-list
port_list
loopback-port
port] { remote-tag
rtag } | remote-ip
remote_ip_address {{ vr } {vr_name } {from [ source_ip_address | auto-source-ip]}{ping-check [on | off]} priority
priority_value
]} {description
mirror-desc}
-
If you want to configure mirroring on
multiple ports, and did not configure this with the above create command, use the following
command using the port-list option:
configure mirror mirror_name {to
[port
port | port-list
port_list | loopback port
port] | remote-ip {add} remote_ip_address {{vr} vr_name } {from [source_ip_address | auto-source-ip]} {ping-check [on | off]}] {remote-tag
rtag | port
none} {priority
priority_value}
The port-list is a list of monitor ports that transmit identical copies of
mirrored packets. The loopback-port is an unused port that is required when you mirror
to a port-list. The loopback-port is not available for switching user data traffic.
Certain L2 control protocol packets, such as STP (Spanning Tree Protocol), LACP, and
LLDP (Link Layer Discovery Protocol), cannot be mirrored with one-to-many mirroring. The remote IP address option allows you enable hardware mirroring of Ethernet frames
to a specified remote IPv4 address, which can reside zero or more router hops away.
For high availability, you can add up to four redundant remote IP addresses.
If you are adding another (redundant) remote IP address to an existing mirror that
already has a remote IP address configured, you must use the add option.
-
Mirroring is disabled by default. To enable mirroring, use
one of the following commands:
- enable mirror mirror_name
- enable mirror to [port
port | port-list
port_list
loopback-port
port] {remote-tag
tag}
- enable mirror {mirror_name} to remote-ip
remote_ip_address {{vr} vr_name} {from [source_ip_address | auto-source-ip]} {ping-check [on | off]}]
-
To disable mirroring, use the following command:
disable mirror [mirror_name | all]
-
To remove one or all remote IP addresses, use the following command:
configure mirror {mirror_name
to
remote-ip
delete [all | remote_ip_address {{vr} vr_name}] }
To delete all or the last remaining remote IP address, you must disable the mirror
first.
