Table 3-10. Inter-Switch Trunk Configuration screen fields
Field Description
Trunk
Column header for the read-only fields in this screen. The read-only data displayed in
the Trunk column indicates the trunks (
I
1 to
I
4) that correspond to the switch ports
specified in the user-configurable Trunk Members fields.
Trunk Members
The Trunk Members column contains fields in each row that can be configured to create
the corresponding trunk. The combined trunks cannot exceed eight trunk members.
Each switch port can only be a member of a single trunk. The appropriate trunk number
for each trunk member configured within this field is shown adjacent to the
corresponding switch port in the following screens: Port Configuration screen, Spanning
Tree Configuration screen, and VLAN Configuration screen.
Default Value blank field
Range 1 to 26 (depending on model type)
STP
The STP column contains a single field for each row that, when enabled, allows the
specified trunk to participate in the spanning tree. This setting overrides those of the
individual trunk members.
Default Value Enabled
Range Enabled, Disabled
Trunk Mode
The Trunk Mode column contains a single field for each row that allows a user to set the
trunk to operate in one of two modes: Basic or Enhanced.
Basic:
Basic mode is the default mode for the switch. When in this mode, the switch
locks a source MAC address to a specific trunk member for a certain time interval. This
allows the switch to stabilize data streams of source addresses within the trunk
members.
Enhanced:
When in this mode, the switch evenly distributes source MAC addresses to
the trunk members, thereby balancing traffic throughout the trunk.
Note:
Certain protocols, such as Local Area Transport (LAT), require proper
sequencing of received packets for correct operation. Using Enhanced mode may cause
some packets to be received out of sequence. If your application is using a protocol
requiring proper sequencing of packets, use the Basic mode.
Default Value Basic
Range Basic, Enhanced
Trunk Status
The Trunk Status column contains a single field for each row that allows users to enable
or disable any of the trunks.
Default Value Disabled
Range Enabled, Disabled
