Stack

The Acer switch supports stacking of Acer switch units. Switch stacking

is created by connecting switches in a daisy chain. One of the stacked

switches is selected as a Master based on its configurations. The Master

switch provides management support for the whole stack. Other

switches in the stack are referred to as slave switches.

Note: Make sure all stacked switches are running the same version

of firmware.

The Master switch manages the control plane traffic for all stacked

switches. When the current master switch fails, the backup master is

then selected as the current master. The Master selection algorithm is

based on a priority configuration. If two switches have the same

priority, the switch with the lowest MAC address is selected as the

Master switch.

Enabling Stacking

By default, Acer switches act as stand-alone switches. This stand-alone

default facilitates using 10G Ethernet ports as Extreme Ethernet ports

for uplinks.

When stacking is enabled the stacking ports are dedicated for stacking

purposes. Stacking can be enabled using the command

stack with the

switch identifier and priority. The detailed command syntax is

explained below.

Note: When stacking is enabled, the switch needs to be rebooted

to make it effective.

Note: When a switch is acting as a stand-alone switch with stacking

disabled, all physical interfaces are numbered as 0/1 to 0/n.

When the switch is in stacking mode, the interfaces are numbered as

<switch id>/1 to <switch id> / n.

In non-stacking mode, the switch ID is considered to be 0.
