Note If you have set the console speed to 115200, you may want to reset it to the previous speed or to the factory default speed (typically 9600 bps). See the "Configuration Register Commands" procedure on page B-7. Copying an Image from a TFTP Server Using the tftpdnld Command The tftpdnld command downloads a Cisco IOS software image from a remote server accessible from a FastEthernet, Ethernet, or Token Ring network interface on a Cisco 2600 series router (except Cisco 2691). The tftpdnld command downloads the Cisco IOS software image into flash memory using TFTP. Restrictions on the tftpdnld Command The following software restrictions apply when using the tftpdnld command: • Ethernet and FastEthernet-Accepts and sends only Ethernet V2.0 data packets. • Token Ring-Accepts and sends only Token Ring frames with IEEE802.3 SNAP frames. Does not support any frames with routing information fields (RIFs), limiting all use of the tftpdnld command to a TFTP server on the local ring. If the TFTP server resides off the local ring, you must establish a path to the server through a router or transparent bridge from the local ring.

Copying an Image from a TFTP Server Using the tftpdnld Command
The
tftpdnld
command downloads a Cisco IOS software image from a remote server accessible from a
FastEthernet, Ethernet, or Token Ring network interface on a Cisco 2600 series router (except Cisco
2691). The
tftpdnld
command downloads the Cisco IOS software image into flash memory using TFTP.
Restrictions on the tftpdnld Command
The following software restrictions apply when using the
tftpdnld
command:
•
Ethernet and FastEthernet—Accepts and sends only Ethernet V2.0 data packets.
•
Token Ring—Accepts and sends only Token Ring frames with IEEE802.3 SNAP frames. Does not
support any frames with routing information fields (RIFs), limiting all use of the
tftpdnld
command
to a TFTP server on the local ring. If the TFTP server resides off the local ring, you must establish
a path to the server through a router or transparent bridge from the local ring.
