Description
The Spanning Tree Protocol (STP) Administrative Mode associated with the port or LAG. STP is a
Layer-2 protocol that provides a tree topology for switches on a bridged LAN. STP allows a network
to have redundant paths without the risk of network loops, by providing a single path between end
stations on a network. The possible values for STP mode are:
• Enabled Spanning tree is enabled for this port.
• Disabled Spanning tree is disabled for this port.
For more information about STP, see "Configuring Spanning Tree Protocol" on page 161.
The administrative mode of the Link Aggregation Control Protocol (LACP). The mode must be enabled
in order for the port to participate in Link Aggregation. This field can have the following values:
Enabled
• The port uses LACP for dynamic LAG configuration. When LACP is enabled, the port
sends and receives LACP Protocol Data Units (PDUs) with its link partner to confirm that the
external switch is also configured for link aggregation.
• Disabled The port supports static LAG configuration only. This mode might be used when the
port is connected to a device that does not support LACP. When a port is added to a LAG as a static
member, it neither transmits nor receives LACP PDUs.
Indicates whether the Link is up or down. The link is the physical connection between the port or LAG
and the interface on another device.
Indicates whether the port will send an SNMP trap when link status changes.
• Enable (Default) The system sends a trap when the link status changes.
Disable
• The system does not send a trap when the link status changes.
The maximum Ethernet frame size the interface supports or is configured to support. The maximum
frame size includes the Ethernet header, CRC, and payload.
The broadcast storm control threshold for the port. If broadcast traffic on the Ethernet port exceeds
this threshold, the system blocks (discards) the broadcast traffic. To configure this threshold (disabled
by default), click Enable, enter a threshold value, and select the units for the threshold:
• % The threshold value specifies a percentage of port speed from 0 to 100 (default: 5).
• pps The threshold value is in packets per second.
The multicast storm control threshold for the port. If multicast traffic on the Ethernet port exceeds this
threshold, the system blocks (discards) the multicast traffic. To configure this threshold (disabled by
default), click Enable, enter a threshold value, and select the units for the threshold:
• % The threshold value specifies a percentage of port speed from 0 to 100 (default: 5).
• pps The threshold value is in packets per second.
The unicast storm control threshold for the port. If unicast traffic on the Ethernet port exceeds this
threshold, the system blocks (discards) the unicast traffic. To configure this threshold (disabled by
default), click Enable, enter a threshold value, and select the units for the threshold:
• % The threshold value specifies a percentage of port speed from 0 to 100 (default: 5).
• pps The threshold value is in packets per second.
