The following current system behavior, configuration statement
usage, and operational mode command usage might not yet be documented
in the JUNOS software documentation:
Class of Service
A new command has been introduced to change the buffering
scheme:
set class-of-service shared-buffers percent value
This option gives you the flexibility of controlling the shared
egressed buffer allocation per interface. Uplink ports are not used
for shared allocation.
Interfaces
The following counters are not supported on routed VLAN
interfaces (RVIs): local statistics, traffic statistics, and transit
statistics.
Virtual Chassis
On EX 4200 switches, if you enter the command request
chassis routing-engine master switch and then enter the command
again within 240 seconds, the switch will display an error message
saying “Command aborted. Not ready for mastership switch, try
after n seconds.”
