Configuring Switching Information

185

ProSafe M5300 Switch

To configure LAG settings:

1. Use LAG Name to enter the name you want assigned to the LAG. You may enter any

string of up to 15 alphanumeric characters. A valid name has to be specified in order to

create the LAG.

2. Use Hash Mode to select the load-balancing mode used on a port-channel (LAG). Traffic is

balanced on a port-channel (LAG) by selecting one of the links in the channel over which to

transmit specific packets. The link is selected by creating a binary pattern from selected

fields in a packet, and associating that pattern with a particular link:

• Src MAC,VLAN,EType,incoming port - Source MAC, VLAN, EtherType, and

incoming port associated with the packet.

• Dest MAC,VLAN,EType,incoming port -Destination MAC, VLAN, EtherType, and

incoming port associated with the packet.

• Src/Dest MAC,VLAN,EType,incoming port - Source/Destination MAC, VLAN,

EtherType, and incoming port associated with the packet.

• Src IP and Src TCP/UDP Port fields - Source IP and Source TCP/UDP fields of the

packet.

• Dest IP and Dest TCP/UDP Port fields - Destination IP and Destination TCP/UDP Port

fields of the packet.

• Src/Dest IP and TCP/UDP Port Fields - Source/Destination IP and source/destination

TCP/UDP Port fields of the packet.

• Enhanced hashing mode - Features MODULO-N operation based on the number of

ports in the LAG, non-Unicast traffic and unicast traffic hashing using a common hash

algorithm, excellent load balancing performance, and packet attributes selection

based on the packet type:

• For L2 packets, source and destination MAC address are used for hash

computation.

• For L3 packets, source IP, destination IP address, TCP/UDP ports are used.

3. Use Link Trap to specify whether you want to have a trap sent when link status changes.

The factory default is enable, which will cause the trap to be sent.

4. Use Admin Mode to select enable or disable from the pull-down menu. When the LAG is

disabled no traffic will flow and LACPDUs will be dropped, but the links that form the LAG

will not be released. The factory default is enable.

5. Use STP Mode to enable or disable the Spanning Tree Protocol Administrative Mode

associated with the LAG. The possible values are:

• Disable - Spanning tree is disabled for this LAG.

• Enable - Spanning tree is enabled for this LAG.

6. Use Static Mode to select enable or disable from the pull-down menu. When the LAG is

enabled it does not transmit or process received LACPDUs i.e. the member ports do not

transmit LACPDUs and all the LACPDUs it may receive are dropped. The factory default is

disable.

7. Click APPLY to update the switch with the changes.

8. Click DELETE to remove the currently selected configured LAG. All ports that were

members of this LAG are removed from the LAG and included in the default VLAN.
