LINK AGGREGATION INTEROPERABILITY OF THE DELL POWERCONNECT 6200 SERIES SWITCH
CISCO AND DELL LAG DISTRIBUTION CONFIGURATION
Switches can only control the distribution of outgoing traffic on LAG ports. The PowerConnect
6200 Series switch supports six different distribution methods based on source and/or
destination MAC or IP addresses, source and/or destination TCP/UDP ports, and source
port/module ID to decide which port or LAG a packet will travel. The default distribution is
based on the source IP and source TCP/UDP port.
The following list shows the distribution methods available on the PowerConnect 6200 Series switch:
1 - Source MAC, VLAN, EtherType, source module and port ID
2 - Destination MAC, VLAN, EtherType, source module and port ID
3 - Source IP and source TCP/UDP port
4 - Destination IP and destination TCP/UDP port
5 - Source/Destination MAC, VLAN, EtherType, source MODID/port
6 - Source/Destination IP and source/destination TCP/UDP port
PC6248#configure
PC6248(config)#interface port-channel 1
PC6248(config-if-ch1)#hashing-mode 1
Cisco IOS and CatOS switches provide configuration options for changing the distribution of
traffic on LAG ports.
One of the following Cisco IOS commands may be useful if poor performance on the LAG
from the Cisco IOS switch is observed. In the order listed, the commands will allow the user to
configure the switch to distribute packets to ports in a LAG based on the destination IP
address, destination Ethernet address, a combination of source and destination IP addresses,
a combination of source and destination Ethernet addresses, source IP address, or source
Ethernet address.
3750(config)#port-channel load-balance dst-ip
3750(config)#port-channel load-balance dst-mac
3750(config)#port-channel load-balance src-dst-ip
3750(config)#port-channel load-balance src-dst-mac
3750(config)#port-channel load-balance src-ip
3750(config)#port-channel load-balance src-mac
One of the following Cisco CatOS commands may be useful if poor performance on the LAG
from the Cisco CatOS switch is observed. In the order listed, the commands will allow the user
to configure the switch to distribute packets to ports in a LAG based on the destination IP
address, destination Ethernet address, a combination of source and destination IP addresses,
a combination of source and destination Ethernet addresses, source IP address, or source
Ethernet address.
