IOS – Flash upgrade

Find correct iOS from Cisco software research site

For IOS upgrade required TFTP server

TFTP- Trivial File Transfer Protocol

Download tftp server from

We have to configure router physical interface to particular IP address in order to access tftp server.

Open tftp server turn On

tftp root directory – move iOS downloaded file to that folder

PSIR_2911(config)# line vty 0 4

PSIR_2911(config-line)#transport input telnet ssh


PSIR_2911(config)#wr mem

now move latest iOS file to flash drive on router

PSIR_2911(config)#copy tftp:// flash:

After complete transfer iOS file. check flash drive file received or Not

PSIR_2911# dir

Now we have to change old booting iOS file to new iOS file path.

PSIR_2911(config)#boot system flash:c2900-universal-mz.SPA.156-2.T2.bin


PSIR_2911#wr mem

PSIR_2911# reload

Now we have old iOS kept in flash drive. we have to remove from the system.

PSIR_2911#dir. – Note on the old file name

PSIR_2911# del flash:c2900-universal……M2.bin

confirm delete old iOS file.

Setting IP address on data vlan and voice vlan using sub interface.

PSIR_2911(config)#interface gigaethernet 0/1

PSIR_2911(config-if)#no ip address


PSIR_2911(config)#interface gigaethernet 0/1.1

PSIR_2911(config-subif)#encapsoluation dot1q 1 native

PSIR_2911(config-subif)#IP address

PSIR_2911(config-subif)#desc interface for data vlan1


PSIR_2911(config)#interface gigaethernet 0/1.10

PSIR_2911(config-subif)#encapsulation dot1q 10

PSIR_2911(config-subif)#IP address

PSIR_2911(config-subif)#desc interface for voice vlan10


PSIR_2911(config)#wr mem

Set time and date

Configure NTP server and DNS access

PSIR_2911(config)#ntp server prefer

PSIR_2911(config)#ntp server

PSIR_2911(config)#ntp server


PSIR_2911#show ntp config

PSIR_2911#show ntp status

PSIR_2911#wr mem

Check and confirm ntp server working well.

Installing UCME GUI

UCME- web based administration , easy configuration of some settings. not installed by default.

Download Cisco UCME from website.

Download file and copy to tftp root folder

start run on tftp server

Open putty and copy UCME file to flash drive

Now enable embedded webserver

PSIR_2911(config)#ip http sever

PSIR_2911(config)#ip http auth local

PSIR_2911(config)#file privilege 0


PSIR_2911(config-telephony)#web admin system name johnGUI secret 0 GUIPass0




PSIR_2911(config)#ip http path flash:/CME-11.6-GUI


PSIR_2911#wr mem

Now finished installation UCME Gui- access from web browser.
