Setting The Ethernet Link Rate - Polycom V2IU 6400-S User Manual

Setting the Ethernet Link Rate

Note
3. For most situations, you should leave this setting as it is. Only change it if
your provider indicates that you should do so. If your provider indicates
that you need to change the ToS byte setting, that provider should also
provide the other parameters required on this screen.
4. If you have changed the values, click Submit to activate the new settings.
Ethernet autonegotiation is often unreliable, especially between different ven-
dors or old and new networking equipment. Failure of autonegotiation is
generally not a cause for concern. However, if the negotiated rates change
intermittently or the link is reported as no link or down, the link rate may
need to be set manually. An interface that "flutters" because of the autonego-
tiation setting, may cause intermittent voice and data outages.
The vast majority of Ethernet networking devices including the 6400-S use
"autonegotiate" as a default setting. Chances are that you will not have to set the
Ethernet link rate. Please use caution if manually configuring the link rate, as a
speed or duplex mismatch will result in a loss of connectivity.
If needed, configure the rate of the physical Ethernet port on the 6400-S. The
default setting for the Ethernet port is autonegotiate, and it applies to both the
link speed and duplex with locally attached devices.
The link rate of an interface can be assigned to a desired rate. A network
administrator may want to set the rate manually if autonegotiation fails to
select a rate consistently or if it selects a rate that is slower than the maximum
rate supported by both interfaces.
To set the link rate:
1. In the navigation bar, select System.
