2.3 Interface mirror
2.3.1 Brief introduction of interface mirror
System provides mirror based on interface, that is, copy packet in a or more specified interface
to monitor interface to analyze and monitor packet. For example, copy packet of Ethernet 0/2
to specified monitor interface Ethernet 0/3 so that test and keep record by protocols linked by
monitor interface Ethernet 0/3.
System also provides packet mirror for specified source/destination MAC address. For
example, mirror packet from Ethernet 0/3 with the destination MAC address of
00:1f:ce:00:00:01.
System also provides mirror divider, that is, sample packet that can be mirrored and send it to
mirror destination interface to reduce the number of packet to mirror destination interface.
2.3.2 Interface mirror configuration
Interface Mirror configuration command includes:
Configure mirror destination interface
Configure mirror source interface
Display interface mirror
Configure mirror interface
Configure mirror destination interface in global configuration mode:
Configure mirror interface
mirror destination-interface interface-num
This command will cancel original mirror destination interface.
Remove mirror interface
no mirror destination-interface interface-num
For example:
! Configure Ethernet 0/0/1 to be mirror interface
QTECH(config)# mirror destination-interface ethernet 0/0/1
Configure mirror source interface
Configure mirror source-interface of switch in global configuration mode:
Configure mirror source-interface
mirror source-interface { interface-list | cpu } { both | egress | ingress }
interface-list is in the form of interface-num [ to interface-num ], which can be repeated for 3
times. Cpu interface is in the form og character string “cpu”
both means mirroregress and ingress interfaces, egress means mirror interface egress and
ingress means mirror interface ingress.
Remove mirror source interface
no mirror source-interface { interface-list | cpu }
For example:
! Configure Ethernet 0/0/1 to Ethernet 0/0/12 to be mirror source interfaces
QTECH(config)# mirror source-interface ethernet 0/0/1 to ethernet 0/0/12 both
! Remove Ethernet 0/0/10 to Ethernet 0/0/12 from mirror source interfaces
QTECH(config)#no mirror source-interface ethernet 0/0/10 to ethernet 0/0/12
Display interface mirror
