The default settings for the default template are described for all commands in line template configuration
mode in the
Terminal Services Commands on
module in
System Management Command Reference for
Cisco NCS 5000 Series Routers
.
Before creating or modifying the vty pools, enable the telnet server using the
telnet server
command in
XR Config mode. See
IP Addresses and Services Configuration Guide for Cisco NCS 5000 Series Routers
and
IP Addresses and Services Command Reference for Cisco NCS 5000 Series Routers
for more
information.
Note
Terminal Identification
The physical terminal lines for the console port is identified by its location, expressed in the format of
rack
/
slot
/
module
, on the active or standby route processor (RP) where the respective console port resides.
For virtual terminals, physical location is not applicable; the Cisco IOS XR software assigns a vty identifier
to vtys according to the order in which the vty connection has been established.
vty Pools
Each virtual line is a member of a pool of connections using a common line template configuration. Multiple
vty pools may exist, each containing a defined number of vtys as configured in the vty pool. The Cisco IOS XR
software supports the following vty pools by default:
•
Default vty pool
—
The default vty pool consists of five vtys (vtys 0 through 4) that each reference the
default line template.
•
Default fault manager pool
—
The default fault manager pool consists of six vtys (vtys 100 through 105)
that each reference the default line template.
In addition to the default vty pool and default fault manager pool, you can also configure a user-defined vty
pool that can reference the default template or a user-defined template.
When configuring vty pools, follow these guidelines:
•
The vty range for the default vty pool must start at vty 0 and must contain a minimum of five vtys.
•
The vty range from 0 through 99 can reference the default vty pool.
•
The vty range from 5 through 99 can reference a user-defined vty pool.
•
The vty range from 100 is reserved for the fault manager vty pool.
•
The vty range for fault manager vty pools must start at vty 100 and must contain a minimum of six vtys.
•
A vty can be a member of only one vty pool. A vty pool configuration will fail if the vty pool includes
a vty that is already in another pool.
•
If you attempt to remove an active vty from the active vty pool when configuring a vty pool, the
configuration for that vty pool will fail.
