Manually Configuring Interface Subgroups - Cisco Nexus 1000V Configuration Manual

Configuring Port Channels

Manually Configuring Interface Subgroups

You can manually configure port channel subgroups to manage the traffic flow on multiple upstream switches.
This action is required for a port channel that connects to multiple upstream switches where CDP is not
configured.
Before You Begin
• Log in to the CLI in EXEC mode.
• Configure the port profile for the port channel using the procedure in
Switches, on page
• Know the interface range and the subgroup IDs (0 to 31) for traffic to the upstream switches.

Step 6
This example shows how to manually configure port channel subgroups for a host in module 3 which has four
physical ports. The upstream switches do not support CDP. Ethernet ports 3/2 and 3/3 connect to one upstream
switch and the Ethernet ports 3/4 and 3/5 connect to another upstream switch.

Creating a Port Profile for a Port Channel
Connecting to Multiple Upstream
Purpose
Enters global configuration mode.
Enters interface configuration mode for the specified
interface range.
Manually configures a subgroup to manage traffic for
the upstream switch. Allowable subgroup numbers are
from 0 to 31.
Perform this step for each port connected to an upstream
switch where CDP is not configured.
(Optional)
Displays the configuration for verification.
(Optional)
Saves the change persistently through reboots and
restarts by copying the running configuration to the
startup configuration.
