# Managing switch pairs

In order to enable the creation of M-LAG or equivalent multi-chassis link aggregations the admins must mark the switches that form pairs.

## Create a switch pair

Ensure both switches are added to the system and configured using either the UI or the `switch create` CLI command. 

Use the CLI to create the switch pair between switch 10 and 20:
1. List the registered switches to get the IDs:
```
metalcloud-cli switch list
+-------+------------+-------------------+-------+-------------+----------+
| ID    | IDENTIFIER | DATACENTER        | DRIVER| PROVISIONER | MGMT IP  |
+-------+------------+-------------------+-------+-------------+----------+
| 4     | sw1-env2   | us12-chi-qts01-dc | os_10 | evpnvxlanl2 | 100.0.1.6 |
| 5     | sw2-env2   | us12-chi-qts01-dc | os_10 | evpnvxlanl2 | 100.0.1.7 |
+-------+------------+-------------------+-------+-------------+----------+
Total: 2 Switches
```
2. Create the switch pair between the two switches
```
metalcloud-cli switch-pair create --switch1 4 --switch2 5
```

## Listing switch pairs
To list the switch pairs to see if the switch pair was created:
```
metalcloud-cli switch-pair list
+-------+---------------+---------------+-------+
| ID    | Switch1       | Switch2       | TYPE  |
+-------+---------------+---------------+-------+
| 5     | sw1-env2 (#4) | sw2-env2 (#5) | mlag  |
+-------+---------------+---------------+-------+
Total: 1 Switch links
```

## Deleting switch pairs

```
metalcloud-cli switch-pair delete --switch1 4 --switch2 5
```
