configure sharing add ports

configure sharing port add ports port_list

Description

Adds ports to a load-sharing, or link aggregation, group. By using link aggregation, you use multiple ports as a single logical port. Link aggregation also provides redundancy because traffic is redistributed to the remaining ports in the link aggregation group (LAG) if one port in the group goes down.

Syntax Description

port Specifies the logical port for a load-sharing group or link aggregation group (LAG). This number also functions as the LAG Group ID.
port_list Specifies one or more ports or slots and ports to be grouped in the LAG.

Default

N/A.

Usage Guidelines

Use this command to dynamically add ports to a load-sharing group, or link aggregation group (LAG).

Note

Note

You must create a LAG (or load-sharing group) before you can configure the LAG. To create a LAG, see enable sharing grouping.

VMAN ports can belong to LAGs. If any port in the LAG is enabled for VMAN, all ports in the group are automatically enabled to handle jumbo size frames. Also, VMAN is automatically enabled on all ports of the untagged LAG.

To verify your configuration, use the show ports sharing command.

Note

Note

All ports that are designated for the LAG must be removed from all VLANs prior to configuring the LAG.

Summit family switches

The following guidelines apply to link aggregation on the Summit family switches:
  • On the Summit X670 in EXOS 15.2 and later, 32 ports per LAG are supported with LACP support and custom load sharing algorithm only. Additionally, a static LAG can contain up to 16 ports and an LACP LAG can include up to 32 ports.
  • One static LAG can contain up to 8 ports.
  • An LACP LAG can include a maximum of 16 ports; out of these up to 8 can be selected links and the remaining 8 will be standby links.
  • A Health Check LAG can contain up to 8 ports.

BlackDiamond 8800 series switch and SummitStack only

The following guidelines apply to link aggregation on the BlackDiamond 8800 series switch:
  • A static LAG can include a maximum of 8 ports.
  • An LACP LAG can include a maximum of 16 ports; out of these up to 8 can be selected links and the remaining 8 will be standby links.
  • A Health Check LAG can include a maximum of 8 ports.

BlackDiamond X8 series switch only

The following guidelines apply to link aggregation on the BlackDiamond X8 series switch:
  • With distributed ARP mode on, the maximum number of aggregator ports on BlackDiamond X8 is 16.
  • With LACP support, but with custom load sharing algorithm only, 64 ports per LAG.

Example

The following example adds port 3:13 to the LAG with the logical port 3:9 on a modular switch:

configure sharing 3:9 add port 3:13
