Table 118. SNMP Traps and OIDs (continued)
OID String OID Name Description
.1.3.6.1.4.1.6027.3.10.1.2.5.1.7 chSysPortXfpRecvTemp OID displays the temperature of the
connected optics.
NOTE: These OIDs only generate
if you enable the enable
optic-info-update-interval
is enabled command.

allocation.
.1.3.6.1.4.1.6027.3.27.1.5 dellNetFpStatsPerPortTable View the forwarding plane statistics
containing the packet buffer usage per
port per stack unit.

per COS per port.
Troubleshooting Packet Loss
The show hardware stack-unit command is intended primarily to troubleshoot packet loss.
To troubleshoot packet loss, use the following commands.
● show hardware stack-unit stack-unit-number cpu data-plane statistics
● show hardware stack-unit stack-unit-number cpu party-bus statistics
● show hardware stack-unit stack-unit-number drops unit unit-number
● show hardware stack-unit stack-unit-number unit unit-number {counters | details | port-
stats [detail] | register | ipmc-replication | table-dump}
● show hardware {ip | ipv6 | mac} {eg-acl | in-acl} stack-unit stack-unit-number port-set 0
pipeline 0-3
● show hardware ip qos stack-unit stack-unit-number port-set 0
● show hardware system-flow layer2 stack-unit stack-unit-number port-set 0 {counters |
pipeline 0-3}
● show hardware drops interface interface
● show hardware buffer-stats-snapshot resource interface interface
● show hardware buffer inteface interface{priority-group { id | all } | queue { id| all} }
buffer-info
● show hardware buffer-stats-snapshot resource interface interface{priority-group { id |
all } | queue { ucast{id | all}{ mcast {id | all} | all}
● show hardware drops interface interface
● clear hardware stack-unit stack-unit-number counters
● clear hardware stack-unit stack-unit-number unit 0-1 counters
● clear hardware stack-unit stack-unit-number cpu data-plane statistics
● clear hardware stack-unit stack-unit-number cpu party-bus statistics
Displaying Drop Counters
To display drop counters, use the following commands.
● Identify which stack unit and port pipe is experiencing internal drops.
show hardware stack-unit stack-unit-number drops [unit unit-number]
● Identify which interface is experiencing internal drops.
