Choosing a high speed flow control mode
The high speed flow control feature allows you to control traffic and avoid
congestion on the Gigabit full-duplex link. If the receive port buffer becomes full,
the Ethernet Switch 425-24T issues a flow-control signal to the device at the other
end of the link to suspend transmission. When the receive buffer is no longer full,
the switch issues a signal to resume the transmission. You can choose Symmetric
or Asymmetric flow control mode.
Symmetric mode
This mode allows both the GBIC port and its link partner to send flow control
pause
frames to each other.
Autonegotiation
Indicates if the Autonegotiation has been enabled on the port. When enabled,
the port only advertises support for 1000 Mb/s operation, in full-duplex mode.
Default Value
Enabled
Range
Enabled, Disabled
Speed/Duplex
Displays if a port is configured to support an Ethernet speed of 10 Mb/s or 100
Mb/s, in half- or full-duplex mode. This field is set (by default) to 1000 Mb/s,
full-duplex for Gigabit ports only.
Default
100Mbs/Half (when Autonegotiation is Disabled)
Range
10Mbs/Half, 10Mbs/Full, 100Mbs/Half, 100Mbs/Full
Flow Control
Indicates if the switch or unit has been configured to control traffic and avoid
congestion on the Gigabit MDA port. Two modes are available (see
a high speed flow control mode”
,” next, for details about the two modes). The
Flow Control field cannot be configured unless you set the Autonegotiation field
value to Disabled.
Default Value
Disabled
Range
Disabled, Symmetric, Asymmetric
Note:
All fields (except the
Unit
field) described in
read-only fields.
