Commands Related to AIM Group

Add AIM group

The command to do that is addaimgrp. Make sure that lines are added and out of alarm.

Syntax: addimagrp (or addaimgrp) "group_num port_type list_of_lines"

IMA group number—Value ranging from 1 to 8

Port type—1-UNI, 2-NNI, 3-STI, 4-Virtual trunks UNI (STI in UNI)

List of lines—List of lines separated by periods

Possible errors are

illegal/invalid/bad parameters

IMA group already exists

one of the lines is not yet enabled

configured port type does not match current mode of card

In the following example, we are adding AIM Group number 1, which uses the UNI port type and includes lines 1, 2, and 3.

Sample Display:

AXIS18.1.13.IMATM.a > addaimgrp 1 1 1.2.3

Add the Channel Route Entry

addchrte

After adding the AIM group, add the channel route entry (with set of VPI values), so as to route the cells, with configured VPIs to a particular AIM group. Without channel route entry, all the cells will be discarded as unknown vpi_vci cells.

Enter the dspchrtes command to display all the channel route entries currently configured for all the AIM groups.

Enter the cnfchrte command to configure a channel route entry.

Configure the AIM Group

The command to configure AIM group is cnfaimgrp.

Syntax

cnfimagrp (or cnfaimgrp) grp max_diff_delay n_res_lns

IMA group number—Value ranging from 1 to 8

Max diff delay—Value between 0 and 50 for Model A IMATM T1/E1; between 0 and 275 for Model B IMATM T1;

between 0 and 200 for Model B IMATM E1

# resilient links—Value between 0 and MAX_PHYS_LINKS
