Setting Speed Options For Auto Negotiation On An Ethernet Interface - HP HSR6800 Configuration Manual

Even though the settings are made on the port group, they are saved on each interface basis rather than
on a port group basis. You can only view the settings in the view of each interface by using the display
current-configuration or display this command.
To configure a manual port group:
Step
1. Enter system view.
2. Create a manual port
group and enter manual
port group view.
3. Assign Ethernet interfaces
to the manual port group.
Setting speed options for auto negotiation on an Ethernet
interface
Speed auto negotiation enables an Ethernet interface to negotiate with its peer for the highest speed that
both ends support by default. You can narrow down the speed option list for negotiation.

As shown in
highest speed of 1000 Mbps. If the transmission rate of each server in the server cluster is 1000 Mbps,
their total transmission rate exceeds the capability of port GigabitEthernet 1/0/4, the port providing
access to the Internet for the servers.
To avoid congestion on GigabitEthernet 1/0/4, set 100 Mbps as the only option available for speed
negotiation on port GigabitEthernet 1/0/1, GigabitEthernet 1/0/2, and GigabitEthernet 1/0/3. As a
result, the transmission rate on each port connected to a server is limited to 100 Mbps.

If you use the group-member
interface-type interface-start-number to
interface-type interface-end-number
command to add multiple ports in batch
to the specified port group, make sure all
these ports are of the same type and on
the same interface card, and the
interface-end-number argument must be
greater than the interface-start-number
argument.
