interface port-channel 

Switch to the port-channel configuration mode.

Syntax
[no] interface port-channel <PORT-CHANNEL-ID>
Parameters

<PORT-CHANNEL-ID> — port-channel group index in the range of [1-32].

Privilege group
config-interface-front-port
Command mode

CONFIG

Example
LTP-16N(configure)# interface port-channel

interface port-channel load-balance polynomial

Sets the polynomial to calculate the CRC.

Syntax
interface port-channel load-balance polynomial <POLYNOMIAL>
no interface port-channel load-balance polynomial
Parameters

<POLYNOMIAL> — polynomial. May take values:

  • 0x8003;
  • 0x8101;
  • 0x84a1;
  • 0x9019.
Privilege group
config-interface-front-port
Command mode

CONFIG

Example
LTP-16N(configure)# interface port-channel load-balance polynomial 0x8101

interface port-channel load-balance hash

Sets the fields in the package from which the hash will be calculated.

Syntax
interface port-channel load-balance hash <PACKAGE-FIELDS>
no interface port-channel load-balance hash
Parameters

<PACKAGE-FIELDS> — fields in the package from which the hash will be calculated. From one to three fields can be selected:

  • src-mac — source MAC address;
  • dst-mac — destination MAC address;
  • vlan — vlan field;
  • ethertype — ethertype field. 
Privilege group
config-interface-front-port
Command mode

CONFIG

Example
LTP-16N(configure)# interface port-channel load-balance hash src-mac vlan ethertype

shutdown

Disables port-channel.

Syntax
[no] shutdown
Parameters

The command does not contain any parameters.

Default value
Enabled
Privilege group
config-interface-front-port
Command mode

IF-PORT-CHANNEL

Example
LTP-16N(config)(if-port-channel-1)# shutdown

vlan allow

Enables VLAN passage on the port-channel.

Syntax
[no] vlan allow <VLAN-ID>
Parameters

<VLAN-ID> — VLAN ID in the range of  [1-4094]. The parameter can be a range or an enumeration (for example: vlan allow 5-7 or vlan allow 1,3,5,7).

Privilege group

psc mode multiplication

Selects balancing mode. Balancing according to the Member-ID = MemberCount* Hash/2^16 formula.

Syntax
psc mode multiplication
Parameters

The command does not contain any parameters.

Default value
psc mode smooth-division
Privilege group
config-interface-front-port
Command mode
