Use show mirror command to display system configuration of current mirror interface, including

monitor port and mirrored port list. Use this command in any configuration mode:

show mirror

For example:

! Display monitor port and mirrored port list

QTECH#show mirror

Delete all port and traffic mirror:

no mirror all

For example:

! Delete all port and traffic mirror

QTECH(config)#no mirror all

2.4 Port LACP convergent configuration

2.4.1 Brief introduction of port convergence

Port convergence is a channel group formed by many ports convergence to realize flow load

sharing for each member. When a link cannot be used, flow of this link will be transferred to

another link to guarantee the smoothness of the flow.

Basic configurations are:

1. 2 static or dynamic channel groups can be configured and at most 12 interface members

can be configured in each group, and at most 8 interfaces can be convergent at the same time

in each group which is determined by up/down status, interface number, LACP priority. Each

group is defined to be a channel group, and the command line is configured around it.

2. Load balance strategy of each group can be divided into source MAC, destination MAC,

source and destination MAC, source IP, destination IP, and source and destination IP. The

default strategy is source MAC.

3. System and interface LACP priority can be configured. The default system priority is

32768, and interface priority is 128. To remove system and interface priority is to restore them

to default ones.

4. LACP protocol of each interface can be configured. In static mode, interface is static

convergent, and LACP protocol does not run; in active mode, interface will initiate LACP

negotiation actively; in passive mode, interface only can response LACP negotiation. When

interconnecting with other device, static mode only can interconnect with static mode; active

can interconnect with active and passive mode, but passive mode only can interconnect with

active mode. The default mode of interface is ACTIVE mode.

Each convergent interface need same layer 2 features, so there are following restrictions to

interfaces in a channel group:

Static convergent interfaces and dynamic convergent interfaces can not be in a same channel

group, but there can be static convergent channel as well as dynamic convergent channel.

1. Each interface in a same channel group must possess the same features as following:

interface speed rate, working mode of full duplex, STP/GVRP/GMRP function, STP cost, STP

interface priority, VLAN features (interface mode, PVID, VLAN belonged to, tag vlan list of

access interface, allowed vlan list of trunk interface) and layer 2 multicast group belonged to.

2. If modifying the feature of one interface in the channel group, other interfaces will be

modified automatically in the same place. The feature refers to point 2.
