Change configuration registry on older Cisco routers
H3I ran across an ancient 2500 series router today and had to go through a password recovery. The rommon version was earlier than any I'd seen before. The help functionality was very lean. Here's how to set the confreg for these geezers./H3PIf the rommon help screen (type H to see it) says

Assign or configure IP addresses on Cisco routers
H3Every active interface on a Cisco router to be used with IP requires an IP address assigned to it. This short recipe describes how to set an interface's IP address./H3PGiven an interface fastethernet1, the IP address 192.168.1.5 with the subnet mask 255.255.255.0 can be assigned to it using

Copy Cisco router config into flash to backup or replace hardware
H3When replacing a faulty router that is not completely dead, it may be possible to copy the startup configuration to the removable flash memory and swap the flash to get the new router up and configured in as short a time as possible. Without this procedure, it will be necessary to manually copy

Increase or change Cisco router log size
H3Messages logged by a router can make troubleshooting problems substantially easier. However, the default size of most Cisco routers is 4096 bytes which typically accomodates fewer than 60 messages. While this may help in many situations, adding some additional space can save the day when a rou
