Note This command works only on chassis supporting 12X link aggregation. This c ommand 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)

Sample Output:
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.
