166 MES3000 Ethernet switch series

Operational state of entry
—
operation execution status:

Active —operation is currently active and in cyclic execution.

Inactive — operation is inactive, in standby mode or available for configuration.

Type of operation
—
IP SLA operation type. Can take one value from the list of supported
operations.
When operation state changes to 'Active', operation statistics is cleared. Statistical data is
accumulated while the operation stays in this state. Statistics is saved when operation cyclic execution
stops and goes into 'Inactive' state until it is put back into the active state again.
For detailed information on the statistics contents, see sections on IP SLA operation types.
5.23.1 ICMP Echo operation
Each time ICMP Echo operation executes, the device sends ICMP Echo request to the destination
address, waits for ICMP Echo reply and measures ICMP packet bi-directional transit time. ICMP Echo
operation also provides information on minimal, average and maximum time values and the total number
of measurements that have failed for any reason.
IP SLA operation creation mode commands
Command line request in IP SLA operation creation mode appears as follows:
console(config-ip-sla)#
Table 5.193 —Commands of IP SLA operation creation mode
Command Value Action
icmp-echo target_address
[source-address
source_address ]
[source­interface
source_interface ]
source_interface :
gi_port(1..8/0/1..24);
te_port(1..8/0/1..4)
Create ICMP Echo operation
- target_address
—
IPv4 address for receiving ICMP Echo request
messages;
- source_address
—
IPv4 address used for placement into ICMP
packet header;
- source_interface
—
port for sending packets.
You can define target-address , source-address , and source-interface parameters only at
the time of operation creation; you will not be able to edit them later. To define other
parameters, remove the existing operation and create a new one.
ICMP Echo operation configuration mode commands
Command line request in ICMP Echo operation configuration mode appears as follows:
console(config-ip-sla-icmp-echo)#
Table 5.194 —ICMP Echo operation configuration mode commands
Command Value/Default value Action
frequency sec
sec : (1..128)/60 sec
Set the frequency of ICMP Echo operation execution in seconds.
-
sec —frequency of ICMP Echo operation execution in seconds.
no frequency Set the default frequency.
timeout msec
msec : ( 1..3600000)/1000
ms
Set ICMP Echo operation timeout in milliseconds.
-
msec —timeout of ICMP Echo operation execution in
milliseconds.
no timeout Set the default timeout.
request-data-size bytes
bytes : (1..1432)/56 bytes
Set the number of bytes transmitted in ICMP packet as a data
(payload).
-
bytes —number of bytes.
no request-data-size Set the default number of bytes.
