v5 v6 10 10 11 11 == Undoing Configurations == 12 Most of the time, just adding the command `no` to the beginning of what you see when you do the command `show configuration` will suffice for undoing configurations, but occasionally you get something like this: 12 Most of the time, just adding the command `no` to the beginning of what you see when you do the command `show configuration` will suffice for undoing configurations, but occasionally you get some message that can be a tad cryptic. 13 === getting rid of telnet VLAN 4 === 14 VLAN 4 was the result of initial telnet configs until we realized we wanted to use Network VLAN 1 for telnet purposes. It was made so that port 0/27 was assigned to VLAN 4 so you can telnet using that port. You get this error if you try to remove VLAN 4 straight up: 13 15 {{{ 14 16 (config)# no vlan 4 15 17 vlan : Can't delete this configuration referred by other configuration. 16 18 }}} 17 This happens when the configs for an interface that you are trying to delete are associated with something else; you need to undo any configurations associated with an interface before you can delete it. In this particular case, VLAN 4 is associated with port 0/27,and you need to undo the configurations to port 0/27 that have to do with vlan 4 before you can get rid of it.19 and you need to undo the configurations to port 0/27 that have to do with vlan 4 before you can get rid of it. 18 20 {{{ 19 21 !(config)# int gi 0/27 … … 28 30 !(config)# save 29 31 }}} 32 33 {{{ 34 interface vlan 3 35 ip address 192.168.5.5 255.255.255.0 36 ip helper-address 192.168.5.1 37 ! 38 (config-if)# no ip address 192.168.5.5 255.255.255.0 39 interface : IP interface is not defined. 40 }}} 41 42 in above circumstance, type "no ip helper-address" at the CLI before trying to remove ip address. 43 44 45 == Command `ppupdate` for updating firmware, not actually needed (6/15) == 46 The manual specified the command `ppupdate` for updating the firmware. This command copies new firmware (i.e. downloaded with ftp) on to the switch's flash memory. parameters usable: 47 48 `ppupdate [test][no-display][-f][no-reload]<file name>` 49 50 * `test` - only tests firmware, but doesn't update the firmware 51 * `no-display` - does not show status messages while firmware is being updated 52 * `-f` - update without confirmation 53 * `no-reload` - does not reboot switch after update, so changes take place after next restart 54 * `file-name` - the firmware, usually named k.img 30 55 31 56 == DHCP/BootP relay agent/IP helper (6/28) ==
