Chapter 11 Switch Configuration 106
The following table describes the labels in this screen.
Table 36 Configuration: Switch Configuration: Link Aggregation
TABLE DESCRIPTION
LACP
System Priority LACP system priority is a number between 0 and 65,355. The switch with
the lowest system priority (and lowest port number if system priority is the
same) becomes the LACP “server”. The LACP “server” controls the
operation of LACP setup. Enter a number to set the priority of an active
port using Link Aggregate Control Protocol (LACP). The smaller the
number, the higher the priority level.
Group Setting
Group ID The field identifies the link aggregation group, that is, one logical link
containing multiple ports
Active Select this option to activate a trunk group.
Dynamic (LACP) Select this check box to enable LACP for a trunk.
Apply Click Apply to save your changes back to the switch.
11.7 DHCP Relay
This section describes the DHCP relay and shows you how to configure the DHCP Relay
screen.
11.7.1 Overview
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual
clients to obtain TCP/IP configuration at start-up from a DHCP server. You can configure the
switch to relay client TCP/IP configuration requests to a DHCP server and the server’s
responses back to the clients.
11.7.2 DHCP Relay Agent Information
The switch can add information to client TCP/IP configuration requests that it relays to a
DHCP server. This helps provide authentication about the source of the requests. You can also
specify additional information for the switch to add to the client TCP/IP configuration requests
that it relays to the DHCP server. Please refer to RFC 3046 for more details.
The DHCP relay agent information feature adds an Agent Information field to the option 82
field of the DHCP headers of client TCP/IP configuration request frames that the switch relays
to a DHCP server. The following lists the DHCP relay agent option 82 information that the
switch sends to the DHCP server:
• Slot ID (1 byte)
• Port ID (1 byte)
• VLAN ID (2 bytes)
