Setting CLNS Parameters
You can specify transmission rates for ES and IS
hello packets, the period for which the router considers ES and IS
hello packets to be valid, and name-to-network service access point
mappings.
clns configuration-time
- Use to specify the rate (in seconds) at which ES hello
and IS hello packets are sent.
- The hello packet recipient creates an adjacency entry
for the router that sent it. If the next hello packet is not received
within the specified interval, the adjacency times out, and the adjacent
node is determined to be unreachable.
- In most cases, leave these parameters at their default
value, which is 10 seconds.
- Example
- host1(config)#clns configuration-time 240
- Use the no version to restore
the default value, 10 seconds.
- See clns configuration-time
clns holding-time
- Use to enable sender of an ES hello or IS hello packet
to specify the length of time you consider the information in these
packets to be valid.
- In most cases, leave these parameters at their default
value, which is 30 seconds.
- Example
- host1(config)#clns holding-time 900
- Use the no version to restore
the default value, 30 seconds.
- See clns holding-time
clns host
- Use to define a name-to-NSAP mapping that can then be
used with commands requiring NSAPs.
- The default is that no
mapping is defined.
- The assigned NSAP name is displayed, where applicable,
in show commands.
- The first character can be either a letter or a number.
- This command is generated after all other CLNS commands
when the configuration file is parsed. As a result, the NVRAM version
of the configuration cannot be edited to specifically change the address
defined in the original clns host command. You must specifically change
any commands that refer to the original address. This affects commands
that accept names, such as the net command.
- Enables dynamic resolution of hostnames to system IDs
(within the NSAP address). The hostname mapping is sent in the LSPs
within the Dynamic Hostname type-length-value (TLV type 137). Display
the TLV by issuing the show isis database detail command.
- Use the show hosts command
to display the mapping.
- Example
- host1(config)#clns host
- Use the no version to restore
the default state of no mapping defined.
- See clns host
