Layer 3 Routing Commands 1673
no frequency
• seconds —Number of seconds between the IP SLAs operations. The range
is 1 to 3600.
Default Configuration
The default is 60 seconds.
Command Mode
IP SLA ICMP Echo Configuration mode (config-ip-sla-echo).
User Guidelines
The IP SLA operation will repeat at a given frequency for the lifetime of the
operation. For example, the ICMP Echo operation with a frequency of 60
sends an ICMP Echo Request packet once every 60 seconds for the lifetime of
the operation. This packet is sent when the operation is started, then is sent
again 60 seconds later.
If an individual IP SLAs operation takes longer to execute than the specified
frequency value, a statistics counter called busy is incremented rather than
immediately repeating the operation.
The recommended guidelines for configuring the frequency, timeout and
threshold commands of the IP SLAs ICMP Echo operation are:
(frequency seconds) > (timeout milliseconds) > (threshold milliseconds).
NOTE: It is recommended to not set the frequency value to less than 60 seconds because the
potential overhead from numerous active operations could significantly affect switch
performance.
This command is supported in IPv4 networks and also for IPv6 networks
where IPv6 addresses are supported.
