Provides step-by-step instructions for configuring an interface link bundle, guiding users through setup, required parameters, and validation procedures for proper operation.
Cisco IOS XR software supports the EtherChannel method for bundling Ethernet interfaces. EtherChannel is a Cisco proprietary technology that allows you to configure multiple links in a bundle but does not check link compatibility automatically. IEEE 802.3ad encapsulation uses Link Aggregation Control Protocol (LACP) to ensure all member links in an Ethernet bundle are compatible.
Incompatible or failed links are automatically removed from the bundle.
Before you begin
-
Create a bundle instance.
-
Map physical interface(s) to the bundle.
-
For an Ethernet bundle to be active, you must perform the same configuration on both connection endpoints of the bundle.
Procedure
|
1. |
Create the Ethernet link bundle.
Example:
Router# configure
Router(config)# interface Bundle-Ether 3
Router(config-if)# ipv4 address 10.1.2.3 255.0.0.0
Router(config-if)# bundle maximum-active links 32 hot-standby
Router(config-if)# bundle minimum-active links 1
Router(config-if)# bundle minimum-active bandwidth 30000000
Router(config-if)# exit
|
|
2. |
Map the physical interfaces to the bundle.
Mixed link bundle mode is supported only when active-standby operation is configured.
Example:
Router(config)# interface HundredGigE 0/0/0/0
Router(config-if)# bundle id 3 mode active
Router(config-if)# no shutdown
Router(config)# exit
Router(config)# interface HundredGigE 0/0/0/1
Router(config-if)# bundle id 3 mode active
Router(config-if)# no shutdown
Router(config-if)# exit
Router(config)# interface HundredGigE 0/0/0/2
Router(config-if)# bundle id 3 mode active
Router(config-if)# no shutdown
Router(config-if)# exit
|
|
3. |
Check the running configuration.
Example:
Router# show running-configuration
configure
interface Bundle-Ether 3
ipv4 address 10.1.2.3 255.0.0.0
bundle maximum-active links 32 hot-standby
bundle minimum-active links 1
bundle minimum-active bandwidth 30000000
!
interface HundredGigE 0/0/0/0
bundle-id 3 mode active
!
interface HundredGigE 0/0/0/1
bundle-id 3 mode active
!
interface HundredGigE 0/0/0/2
bundle-id 3 mode active
!
|
|
4. |
Use the show bundle bundle-ether 3 to verify that interfaces forming the bundle are active and the status of the bundle is Up.
Example:
Router# show bundle bundle-ether 3
Tue Feb 4 18:24:25.313 UTC
Bundle-Ether1
