To configure an entry in the ATM E.164 translation table, use the e164 address ATM E.164 translation table configuration command.
e164 address e164-address nsap-address nsap-address
e164-address | Specifies the E.164 address for an entry in the ATM E.164 translation table. The address consists of 7 to 15-decimal digits. See ITU-T Recommendation E.164 for details on the syntax and semantics of native E.164 addresses. |
nsap-address | Specifies the NSAP-encoded ATM end system address for an entry in the ATM E.164 translation table. The address is specified as 40 hexadecimal digits. |
ATM E.164 translation table configuration
Each entry in the ATM E.164 translation table specifies a one-to-one correspondence between a native E.164 address and an NSAP-encoded ATM end system address. Refer to the atm e164 translation command for more information and usage guidelines about the ATM E.164 translation feature.
The e164 address command is a subcommand of the atm e164 translation-table global configuration command.
The following example shows setting an entry in the ATM E.164 translation table.
Switch(config)# atm e164 translation-table Switch(config-atm-e164)# e164 address 1112222 nsap-address 11.111122223333444455556666.112233445566.11
To configure the PNNI peer group leader election, use the election PNNI node configuration command. To set the election parameters to their defaults, use the no form of this command.
election [leadership-priority number] [override-unanimity-timer secs] [pgl-init-timer secs]
number | Peer group leadership priority this node should advertise, in the range of 0 to 205. The default is 0. |
override-unanimity-timer | Specifies the amount of time, in seconds, a node will wait to be declared the preferred peer group leader (PGL) by unanimous agreement among its peers. This timer is used to prevent nodes from waiting forever for unanimity. The default is 30 seconds. |
pgl-init-timer | Specifies the amount of time, in seconds, allowed to initialize the PGL before starting the election process. This timer is used to ensure that every node casts a vote only after waiting for topology information to propagate across the group. The default is 15 seconds. |
reelection-timer | Specifies the amount of time, in seconds, to wait before the reelection process is restarted after connectivity to the PGL is lost. This timer is used to delay each node in the peer group from voting for the PGL upon loss of connectivity until the nodes in the peer group have received updated topology information. The default is 15 seconds. |
secs | The number of seconds for each timer, in the range of 1 to 120. |
See the syntax descriptions.
PNNI node configuration
The node with the highest configured leadership priority in the peer group is normally elected to become the peer group leader. The timers are defined in the PNNI PGL election state machine.
The following example shows how to enter PNNI node configuration mode and specify a node.
Switch(config)# atm router pnni Switch(config-atm-router)# node 1 Switch(config-pnni-node)#
The following example shows how to specify the peer group leadership priority for this node using the default timers.
Switch(config-pnni-node)# election leadership-priority 1
Before you can use a serial port for Frame Relay, use the encapsulation frame-relay interface configuration command. To disable configuration, use the no form of this command.
encapsulation frame-relay ietf
ietf | Sets the encapsulation method to comply with the IETF standard RFC 1490. |
The default encapsulation type is Cisco if you do not use the keyword ietf.
Interface configuration
Although Cisco encapsulation is not available, a serial port configured with ietf encapsulation on the ATM switch is interoperable with a serial port configured with Cisco encapsulation on a router. You have interoperability as long as the connection is for Frame Relay to ATM network interworking or Frame Relay to Frame Relay switching. For Frame Relay to ATM service interworking, configure only ietf encapsulation on the ATM switch and the router serial interfaces.
The following example configures a serial interface for Frame Relay encapsulation type IETF.
Switch(config)# interface serial 11/0/0:1 Switch(config-if)# encapsulation frame-relay ietf
show interface
To erase flash or configuration memory, use one of the erase privileged EXEC commands. The erase startup-config command replaces the write erase command.
erase {flash | startup-config}
flash | Erases internal flash memory. |
startup-config | Erases the startup configuration in memory. |
Privileged EXEC
When you use the erase startup-config command, the switch erases or deletes the configuration pointed to by the config_file environment variable. The config_file environment variable specifies the configuration file used for initialization. If the config_file environment variable specifies a Flash memory device and configuration filename, the switch deletes the configuration file. That is, the switch marks the file as "deleted."
If you attempt to erase the configuration file specified by the config_file or BOOTLDR environment variables, the system prompts you to confirm the deletion. Also, if you attempt to erase the last valid system image specified in the BOOT environment variable, the system prompts you to confirm the deletion.
The following example deletes the startup configuration file.
Switch# erase startup-config
boot config
cd
dialer-list list
show boot
show startup-config
undelete
