cisco switches, routers, configuration archiving

Summary and archiving of the major differences between models of the main configuration and I hope to share with everyone!!

1900 basic configuration:

Switch (config) # hostname1900

Switch (config) # enablepasswordlevel1-15 password (the user EXEC level is 1 to privilege EXEC level 15)

Switch (config) # enablesecretquansheng

Switch (config) # lineconsole0

Switch (config-line) # passwordquansheng

Switch (config) # linevty015 ( To telnet password)

Switch (config-line) # passwordquansheng

Switch (config-line) # login

1900IP address: (with the 2950 difference: 1900 into the interface mode 2950 into the VLAN)

1900vlanvtp configuration:

1900 (config) # vtpdomain domain name (must have)

1900 (config) # vtpserver | client | transparent (set the switch to the server | client | transparent, enabled by default server)

1900 (config) # vtppassword password (set a password, send VTP messages with other switches match)

1900 ( config) # vtppruningenable | disable (enabled by default trimming)

1900 Relay Configuration:

1900 (config) # interfacef0 / 1

1900 (config-if) # trunkon | off | desirable | auto (remember the 1900 supports ISL trunking, showtrunkA | B, Interface A refers to f0/26, B refers to f0/27)

1. Password Recovery

1. in the configuration mode changes to register

Router (config) # config-register0×2142 (modified register value) ” / P> 2. in the ROMMonitor mode change register and to restore passwords

a. Restart the router, press CTRL-BREAK to enter ROMMON mode

b.rommon5> confreg0×2142 or> o/r0×2142 (2500 router does not Support confreg), (to skip the NVRAM configuration information)

c.Router # configmemory (restore NVRAM)

d.Router (config) # enablesecretsisco (reset the password)

e.Router (config) # config-register0×2102 (restore register values)

f.Router # copyrunning-configstartup-config (Save Configuration)
