Limitations of Top Talker monitors, Trunk monitoring

Page 431 highlights

Trunk monitoring 17 The output is sorted based on the data rate of each flow. If you do not specify the number of flows to display, then the command displays the top 8 flows or the total number of flows, whichever is less. The command can display a maximum of 32 flows. For example, to display the top 5 flows on for domain 1 in WWN (default) format: perfttmon --show dom 1 5 To display the top flows on domain 2 in PID format: perfttmon --show dom 2 pid Example switch:admin> perfttmon --show dom 2 pid Src_PID Dst_PID MB/sec Potential E-Ports 0x03f600 0x011300 121.748 2/0,2/2,2/3 0x03f600 0x011300 121.748 3/14,3/15 Limitations of Top Talker monitors Be aware of the following when using Top Talker monitors: • Top Talker monitors cannot detect transient surges in traffic through a given flow. • You cannot install a Top Talker monitor on a mirrored port. • Top Talker can monitor only 10,000 flows at a time. • Top Talker is not supported on VE_Ports, EX_Ports, and VEX_Ports. • The maximum number of F_Port Top Talker monitors on an ASIC is 8. If Virtual Fabrics is enabled, the maximum number of F_Port Top Talker monitors on an ASIC is 4. Trunk monitoring To monitor E_Port (ISL) and F_Port trunks, you can set monitors only on the master port of the trunk. If the master changes, the monitor automatically moves to the new master port. If a monitor is installed on a port that later becomes a slave port when a trunk comes up, the monitor automatically moves to the master port of the trunk. Note the following: • End-to-end monitors are not supported for ISLs. • For F_Port trunks, end-to-end masks are allowed only on the F_Port trunk master. Unlike the monitors, if the master changes, the mask does not automatically move to the new master port. • Brocade 300 platforms support eight filter-based monitors for trunks. • The Brocade 4100, 4900, 5000, 5100, 5300, 5410, 5424, 5450, 5480, 7500, 7500E, 7600, 7800, 8000, 48000, Brocade Encryption Switch, Brocade DCX, and DCX-4S platforms support 12 filter-based monitors for trunks. • For the Brocade 8000, trunk monitoring is supported only on the FC ports and not on the CEE ports.

Trunk monitoring
17
The output is sorted based on the data rate of each flow. If you do not specify the number of
flows to display, then the command displays the top 8 flows or the total number of flows,
whichever is less. The command can display a maximum of 32 flows.
For example, to display the top 5 flows on for domain 1 in WWN (default) format:
perfttmon --show dom 1 5
To display the top flows on domain 2 in PID format:
perfttmon --show dom 2 pid
Example
switch:admin>
perfttmon --show dom 2 pid

Limitations of Top Talker monitors
Be aware of the following when using Top Talker monitors:
Top Talker monitors cannot detect transient surges in traffic through a given flow.
You cannot install a Top Talker monitor on a mirrored port.
Top Talker can monitor only 10,000 flows at a time.
Top Talker is not supported on VE_Ports, EX_Ports, and VEX_Ports.
The maximum number of F_Port Top Talker monitors on an ASIC is 8. If Virtual Fabrics is
enabled, the maximum number of F_Port Top Talker monitors on an ASIC is 4.
Trunk monitoring
To monitor E_Port (ISL) and F_Port trunks, you can set monitors only on the master port of the
trunk. If the master changes, the monitor automatically moves to the new master port.
If a monitor is installed on a port that later becomes a slave port when a trunk comes up, the
monitor automatically moves to the master port of the trunk.
Note the following:
End-to-end monitors are not supported for ISLs.
For F_Port trunks, end-to-end masks are allowed only on the F_Port trunk master. Unlike the
monitors, if the master changes, the mask does not automatically move to the new master
port.
Brocade 300 platforms support eight filter-based monitors for trunks.
The Brocade 4100, 4900, 5000, 5100, 5300, 5410, 5424, 5450, 5480, 7500, 7500E,
7600, 7800, 8000, 48000, Brocade Encryption Switch, Brocade DCX, and DCX-4S platforms
support 12 filter-based monitors for trunks.
For the Brocade 8000, trunk monitoring is supported only on the FC ports and not on the CEE
ports.
