Note This command works only on chassis supporting 12X link aggregation. This command enables 12X link aggregation so that internal switching will be 12X. External ports remain configured to 4X and do not require special cabling configuration to function correctly. Using this function without the option enable12xBit displays current values of a port. A reboot is required to activate changes made with this command. This reboot will be disruptive and will cause the affected switch chips to be reset and have a part of their EEPROM to be reloaded.

ismChassisSetMtu

View/Set/Unset chassis maximum packet MTU size (all ports)

Syntax:

ismChassisSetMtu [mtu]

Options:

[mtu]

4=2048, 5=4096.

Sample Output:

MasterSpine5-> ismChassisSetMtu 4

REBOOT of ALL DEVICES is REQUIRED to activate changes made with ismChassisSetMtu

Note REBOOT of ALL DEVICES is REQUIRED to activate changes made with ismChassisSetMtu. This command will set maximum packet mtu size for both Internal AND External switching. Calling this function without an mtu designator will display the ports' current value. A reboot is required to activate changes made with this command. This reboot will be disruptive and will cause the affected switch chips to be reset and have a part of their EEPROM to be reloaded.

ismIslSetSpeed

Allows the user to view and set internal port link speeds to 2.5 (SDR), 5.0 (DDR) or AutoNegotiate.

Syntax:

ismIslSetSpeed [speedFlag]

Options:

-speedFlag

1 = 2.5, 2 = 5.0, 3 = AutoNegotiate.

Sample Output:

-> ismIslSetSpeed

L01S3Ba link speed is AUTO NEGOTIATE

L01S1Ba link speed is AUTO NEGOTIATE

L01S1Bb link speed is AUTO NEGOTIATE

L03S1Ba link speed is fixed 2.5 (SDR only device)

L03S3Ba link speed is fixed 2.5 (SDR only device)
