Procedures for Recovering Boot and System Images
•
TR_SPEED_MODE—Sets the Token Ring speed and duplex mode. 0=4 Mbps half-duplex mode,
1=4 Mbps full-duplex mode, 2=16 Mbps half-duplex mode, 3=16 Mbps full-duplex mode. The
default is 2.
Note
Specify the TR_SPEED_MODE variable only for routers with a Token Ring network
interface; or for routers with both an Ethernet and a Token Ring port, those routers that
are set to use the Token Ring port with the tftpdnld command.
•
TR_1E1R_PORT—Sets the port to be used with the tftpdnld command. 0=Use Ethernet port,
1=Use Token Ring port. The default is 0.
Note
Specify the TR_1E1R_PORT variable only for those routers with both an Ethernet and
a Token Ring port.
After you specify the variables, you must reenter the tftpdnld command. For example:
rommon 1 > IP_ADDRESS=172.15.19.11
rommon 2 > IP_SUBNET_MASK=255.255.255.0
rommon 3 > DEFAULT_GATEWAY=172.16.19.1
rommon 4 > TFTP_SERVER=172.15.20.10
rommon 5 > TFTP_FILE=/tftpboot/c2600-i-mz
rommon 6 > tftpdnld
IP_ADDRESS=172.15.19.11
IP_SUBNET_MASK=255.255.255.0
DEFAULT_GATEWAY=172.16.19.1
TFTP_SERVER=172.15.20.10
TFTP_FILE=/tftpboot/2600-i-mz
Invoke this command for disaster recovery only.
