Configuring Aggregation Mode
You configure the aggregation mode for calculating metrics and attributes for aggregated PNNI links and
nodes advertised to higher PNNI levels. The ATM switch router has two algorithms to perform link and
node aggregation: best link and aggressive.
To configure link or node aggregation, perform the following steps, beginning in global configuration
mode:
Examples
The following example shows how to configure aggressive link aggregation mode for constant bit rate
(CBR) traffic:
Switch(config)# atm router pnni
Switch(config-pnni-node)# node 2
Switch(config-pnni-node)# aggregation-mode link cbr aggressive
The following example shows how to configure best link aggregation mode for variable bit rate real time
(VBR-RT) traffic on node 2:
Switch(config)# atm router pnni
Switch(config-pnni-node)# node 2
Switch(config-pnni-node)# aggregation-mode node vbr-rt best-link
Displaying the Aggregation Mode Configuration
To display the aggregation mode configuration, enter the following commands in EXEC mode:
Command Purpose
Step 1
Switch(config)# atm router pnni
Switch(config-atm-router)#
Enters ATM router PNNI mode.
Step 2
Switch(config-atm-router)# node node-index
Switch(config-pnni-node)#
Enters node configuration mode and specify the
local node you want to configure.
Step 3
Switch(config-pnni-node)# aggregation-mode
{link | node} {abr | cbr | ubr | vbr-rt | vbr-nrt |
all} {best-link | aggressive}
Configures the service category and aggregation
mode for a link or a complex node.
Command Purpose
show atm pnni aggregation link Displays the link aggregation mode.
show atm pnni aggregation node Displays the node aggregation mode.
