5.13 Configuring EtherAggregate
An EtherAggregate consists of individual Gigabit Ethernet links bundled into a single logical link. The EtherAggregate
feature allows you to manually configure multiple high-speed load-sharing links between two switch/routers or a
switch/router and a server. You can configure up to four Gigabit ports as an aggregated port, which will form into a
logical/virtual interface, supporting transfer rates of up to four Gbps of bi-directional traffic.
In addition to enabling loadsharing of traffic, EtherAggregate provides redundant, alternate paths for traffic if any of
the segments fail.
NOTE:
The ports in an EtherAggregate make a single logical link. Therefore, all the ports in an EtherAggregate must
be connected to the same device at the other end.
5.13.1 Configuring L2 EtherAggregate
An EtherAggregate can be created using the following commands available in configuration mode. The newly created
EtherAggregate will have a unique identifier. The available identifier will be 1–6, which means you can create 6
EtherAggregates with a maximum of 4 physical ports (eth1-eth16) in each EtherAggregate.
Command Purpose
interface port-aggregate
<port-
aggregate-id>
Enter aggregate configuration mode, which is required for all
the following commands.
access
{vlan <vlan#>}
Configure an EtherAggregate group as an access mode.
description
<line>
Add an aggregate specific description.
dot1qtrunk native vlan
<#>
or
dot1qtrunk allowed vlan
[add | remove
| except] <VLAN list> [all | none]
Set dot1qtrunk characteristics:
allowed
: Set the list of allowed VLANs that can receive/send
traffic on this aggregate in tagged format
native
: Set native VLAN for sending and receiving untagged
traffic.
Specify a VLAN list as a single VLAN number or a continuous
range of VLANs described by two VLAN numbers separated
by a hyphen; for example 2,4,5,6,8 or 2,4-6,8
mode [access | dot1q-trunk]
VLAN membership mode of this ether-aggregate group:
access-mode VLAN or dot1q trunk mode VLAN. The default
mode is access-mode VLAN, so the
no
form of the command
will reset it to access-mode. In dot1q trunk mode, the default
value of the native VLAN is 1 and the default allowed-vlan list
contains all VLANs.
name
Aggregate name configuration.
port-member add
<list>
Add the defined list of interfaces to the EtherAggregate. The
