Monitoring Probe-Based Failure Detection

You can monitor probe-based failure detection by using the dladm show-aggr, dlstat show-aggr, and ipadm show-addr commands.

Example 2-7  Displaying Probe-Related Information

The following example displays the statistics of the probes for a DLMP aggregation. With the probe type –P option, you can provide a comma-separated list of arguments (t for transitive probe, i for ICMP probe, and all for both ICMP and transitive probes) in the dlstat show-aggr command to display the probes of the respective probe type.

# dlstat show-aggr -n -P t,i aggr1
   TIME     AGGR     PORT   LOCAL        TARGET       PROBE  NETRTT     RTT
   0.53s    aggr1    net0   net0         net1         t16148  --         --
   0.53s    aggr1    net0   net0         net1         t16148  0.62ms     0.87ms
   1.17s    aggr1    net1   net1         net0         t16148  --         --
   1.17s    aggr1    net1   net1         net0         t16148  0.72ms     0.99ms
   2.24s    aggr1    net1   192.168.0.1  192.168.0.2  i15535  --         --
   2.24s    aggr1    net1   192.168.0.1  192.168.0.2  i15535  0.11ms     0.55ms

TIME

Time at which the probe is sent in seconds. This time is relative to the time when you issue the dlstat command. If the probe is sent before you issue the dlstat command, the time is negative.

AGGR

Aggregation name for which the probe is sent.

LOCAL

ICMP probes: Source IP address of the probes.

Transitive probes: Port name from which the transitive probe originated.

TARGET

ICMP probes: Destination IP address of the probes.

Transitive probes: Port name of the probe that is targeted.

PROBE

Identifier number representing the probe. The prefix t is for transitive probes and the prefix i is for ICMP probes.

NETRTT

Network round-trip-time for the probe. This value is the time period between sending the probe and receiving the acknowledgment by the DLMP aggregation.

RTT

Total round-trip-time for the probe. This value is the time period between sending the probe and completing the process of acknowledgment by the DLMP aggregation.

For more information, see the dlstat (1M) man page.

Example 2-8  Displaying Detailed Information About the Aggregated Port

The following example displays the detailed aggregation information on each underlying port.

# dladm show-aggr -x
LINK       PORT   SPEED  DUPLEX   STATE   ADDRESS            PORTSTATE
aggr1      --     100Mb  full     up      1e:34:db:fa:50:a2  --
           net0   100Mb  full     up      1e:34:db:fa:50:a2  attached
           net1   100Mb  full     up      b2:c0:6a:3e:c5:b5  attached

For more information, see the dladm (1M) man page.

Example 2-9  Displaying the State of the Aggregated Ports

The following example shows the state of the ports of the aggregation and the target IP addresses of the ports.

# dladm show-aggr -S -n
LINK       PORT       FLAGS   STATE    TARGETS        XTARGETS
aggr1      net1       u--3    active   192.168.0.2    net0
--         net0       u-2-    active   --             net1

Example 2-10  Displaying probe-ip Property Values

The following example displays the details about the link property probe-ip for the specified DLMP aggregation.

# dladm show-linkprop -p probe-ip aggr1
LINK     PROPERTY         PERM   VALUE         EFFECTIVE    DEFAULT      POSSIBLE
aggr1    probe-ip         rw     192.168.0.2   192.168.0.2  --	          -- 

Example 2-11  Displaying the IP Address and the State of the Aggregation

The following example displays the IP address and the state of the aggregation.

# ipadm show-addr aggr1
ADDROBJ           TYPE     STATE        ADDR
aggr1/local1      static   ok           192.168.0.1/24
