Port Disable You can configure a “Port Disable” rule to administratively disable an interface when matching a
policy rule. To make the interface operational again, the port must be unplugged/plugged back or
disabled/enabled using “interfaces s/p admin down” and “interfaces s/p admin up”.
Also, a SNMP trap will be sent when an interface goes down when matching a port disable rule.
SNMP Traps A “pktDrop’ SNMP trap will be sent out to the SNMP station when a port goes down because of a
user-port shutdown profile or a port disable rule.
Port Monitoring The same unit cannot support both mirroring and monitoring configuration i.e. a user cannot have a
port monitoring and a port mirroring session on the same unit
Only one monitoring session at a time across the entire system
Only the first 64 bytes of the packet can be monitored. Due to the port monitoring file size, the system
can only store the first 2K packets (i.e. 140K/64 = 2187)
Enabling the monitoring function affects the performance. As every single monitored packet is
enqueued to the CPU, the Q-Dispatcher has to de-queue and look at each and every packet to
determine if the destination is PMM (port monitoring module). The performance will be limited by the
efficiency of Q-Dispatcher de-queuing speed and also the speed at which PMM can get the packets
from Q-Dispatcher through IPC. Due to the performance limitations, monitoring wire rate traffic is not
possible at this time.
The packets coming to CPU are always tagged and undergo the same FFP modifications as mirroring
Port Monitoring not supported on Link Agg.
Port Mirroring The N-to-1 port mirroring allows the user to specify multiple numbers of ports, range of ports as
mirrored source in a single command. However the maximum number of mirror source ports could be
set to 24 for the current release. A user can mirror multiple 10GigE towards 1 port GigE. Of course if
more than 1 GigE of traffic we don't expect one to mirror more that the port can deliver
Aggregate ports are allowed to be mirrored on the physical ports. Mirroring on the logical link
aggregated port ID is not supported.
In mirroring, the packet coming out of mirroring port may be different from the ingress packet, based
on the type of switching. For all types of mirroring, the mirrored packet carries the FFP (Fast Filtering
Processor) modification, mirrored packet may get modified.
To mirror port 1/1 to port 1/4, you can choose the following options:
• In-port
• Out-port
• Bi-directional
Port Mapping Port mapping feature is supported on both OS6800s & OS6850s.
Following are the limitations for the feature
