3. After convergence, static hardware item (ARL, MARL, PTABLE, VTABLE) will be

modified, but there will be delay.

4. After convergence, only host interface can send CPU packet. If STP changes status of

some interface, the status of the whole channel group will be changed.

5. After convergence, when transferring layer 2 protocol packet, STP/GARP/GNLINK will

not transfer packet to the current channel grou. If transferring to other channel group, only one

packet will be transferred.

If there are members in the channel group, this channel group cannot be deleted. Delete

interface members first.

Influence on choosing link redundancy caused by LACP system and interface priority. LACP

provides link redundancy mechanism which needs to guarantee the redundancy consistency of

two interconnected switches and user can configure redundancy link which is realized by system

and interface priority. The redundancy choosing follows the following steps:

First, determine which switch is the choosing standard. For LACP packets interaction, each of

the two switches knows each other’s LACP system priority and system MAC and compares the

LACP system priority to choose the smaller one; if the system priority is the same, compare

MAC and choose the smaller one.

Then, choose redundancy link according to the interface parameter of the chosen switch.

Compare interface LACP priority, and choose the inferior one to be redundant. If the priorities

are the same, choose the interface whose interface number is larger to be redundant.

2.4.2 Interface convergent configuration

Port LACP configuration command includes:

 Channel group configuration

Please configure it in global configuration mode:

channel-group channel-group-number

Parameter “channel-group-number” is range from 0 to 5.

For example:

! Create a channel group with the group number being 0

QTECH(config)#channel-group 0

 Delete channel group

 no channel-group channel-group-number

 Add add port members to the group

channel-group channel-group-number mode {active | passive | on}

In interface configuration mode, add current interface to channel group and specify the mode of

interface. If the channel group doesn’t exist, create it.

For example:

! Add Ethernet 0/3 to channel-group 3 and specify the port to be active mode

QTECH(config-if-ethernet-0/0/3)#channel-group 3 mode active

 Delete interface member in channel group
