LINK AGGREGATION INTEROPERABILITY OF THE DELL POWERCONNECT 6200 SERIES SWITCH
To set a Cisco IOS based switch to the default configuration, use the following commands:
NOTE: This will erase any configuration data previously configured and reboot the switch.
3750# delete flash:/config.text
3750# reload
To set a Cisco CatOS based switch (e.g. Catalyst 6509) to default configuration, use the
following commands:
NOTE: This will erase any configuration data previously configured and reboot the switch.
Cat_6509 (enable) clear config all
Please see other sections of this paper for cases when it is impractical to reset the switches to
factory defaults.
The Dell PowerConnect 6200 Series switch can support up to 18 different LAGs. A port
channel can have from zero to eight of the ports as members. Any external or internal port can be a
member of a LAG. The examples in this document show different numbers of ports in a LAG.
It is recommended that you physically disconnect the ports to be aggregated on both the Cisco
and Dell switches during configuration. This will avoid any network loops being formed before
the LAGs are set up.
CONFIGURING THE 6200 SERIES SWITCH PORTS FOR DYNAMIC
LINK AGGREGATION
The following example shows the Dell PowerConnect 6200 Series switch CLI commands for
configuring eight ports on the switch for LACP.
PC6248(config)# interface range ethernet 1/g17-1/g20
PC6248(config-if)# channel-group 1 mode auto
COMMAND DESCRIPTION
interface range ethernet 1/g17-1/g20
Sets the CLI mode to configure the eight Gigabit Ethernet ports
(referred to in the command as 1/g17-1/g20, which stands
for Gigabit Ethernet ports 17 through 20 on unit 1).
Value ‘1’ in “1/g17 and 1/g20” specifies the unit number, this
number depends on the Stack unit number and can be between
1 to 12. When used in a stacked environment, the member ports
of the LAG can be chosen from across the stack units.
NOTE: All 4 ports do not have to be selected; a LAG can have
0-8 ports depending on the requirements of the network (i.e the
more ports in the LAG, the more bandwidth and more
redundancy that is available). A LAG can even be configured
without any member ports. When ports are added to the LAG,
they will be set to the configuration of the LAG.
channel-group 1 mode auto
Aggregates the four ports into a LAG (referred to in the
command as channel-group), which will use LACP (referred
to in the command as mode auto). The ‘1’ for the channel-group
number only has meaning within the switch and is used to
differentiate up to eighteen unique channel-groups. For each
LAG created, the user will need to choose a number between
one and eighteen, for up to the maximum of eighteen groups.
Both external and the internal ports can be part of LAG.
