port connect independent-as

Function

The port connect independent-as command enables the independent mode on the fabric port that connects the parent to a level-1 AS.

The undo port connect command restores the default mode of the fabric port that connects the parent to a level-1 AS.

By default, the service configuration mode of the fabric port that connects the parent to a level-1 AS is centralized mode.

This command can only be executed on a parent switch.

Format

port connect independent-as

undo port connect

Parameters

None

Views

Fabric port view

Default Level

3: Management level

Usage Guidelines

Usage Scenario

In independent mode, you can log in to an AS to configure this AS using commands. After the independent mode is enabled on the fabric port that connects the parent to a level-1 AS, the level-1 AS can be configured independently.

Precautions

Before enabling the independent mode, run the independent-as-admin command in the uni-mng view to configure an administrator for AS login.
If the AS connected to a fabric port is online, running the undo port connect command on the fabric port for mode switching will cause the AS to automatically restart and register with the parent again.
During mode switching on a fabric port, the parent and AS exchange packets for multiple times. In this process, if faults occur, for example, link or device faults, mode switching may fail. An error message will be displayed on the parent, indicating that mode switching fails. Additionally, the AS may restart and then registers with the parent again. In this situation, run commands on the fabric port again to change the mode after the AS has registered with the parent.
In independent mode, when an AS goes offline, traffic on the network attached to an AS port cannot be forwarded if the port has authentication configurations. To enable the traffic to be forwarded normally, manually delete the authentication configurations from the port.

When the service configuration mode of an AS is independent mode, configuring the following commands on the Eth-Trunk bound to or on the member port of a fabric port connected to the AS may cause this AS to go offline.

**Table 1** Commands that may cause an AS to go offline
No.	Command
1	loopback internal
2	traffic-policy
3	traffic-filter
4	speed
5	negotiation
6	port media-type
7	port split
8	training disable
9	wavelength-channel
10	undo port hybrid tagged vlan
11	undo port trunk allow-pass vlan
12	storm-control action
13	mac-address flapping action
14	port-security protect-action

If the Eth-Trunk bound to a fabric port has other configurations in addition to the following configurations, you need to manually delete the other configurations before running the undo port connect command on this fabric port for mode switching. Otherwise, an error message will be displayed to indicate that mode switching fails.

**Table 2** Commands that do not need to be manually deleted in an Eth-Trunk
No.	Command
1	port link-type hybrid
2	port hybrid tagged vlan
3	undo port hybrid vlan
4	stp root-protection
5	stp edged-port disable
6	loop-detection disable
7	mode lacp
8	mad relay
9	trust 8021p
10	authentication-profile
11	authentication control-point
