Dear Experts, I have bought a new Cisco ISR 2901 router. When i initially starts it, this msg comes.... ----------------------------------------------------------------------- Cisco Configuration Professional (Cisco CP) is installed on this device. This feature requires the one-time use of the username "cisco" with the password "cisco". These default credentials have a privilege level of 15. YOU MUST USE CISCO CP or the CISCO IOS CLI TO CHANGE THESE PUBLICLY-KNOWN CREDENTIALS Here are the Cisco IOS commands. username <myuser> privilege 15 secret 0 <mypassword> no username cisco Replace <myuser> and <mypassword> with the username and password you want to use. IF YOU DO NOT CHANGE THE PUBLICLY-KNOWN CREDENTIALS, YOU WILL NOT BE ABLE TO LOG INTO THE DEVICE AGAIN AFTER YOU HAVE LOGGED OFF. For more information about Cisco CP please follow the instructions in the QUICK START GUIDE for your router or go to http://www.cisco.com/go/ciscocp ----------------------------------------------------------------------- Now unfortunately Loged off after 1st time loging in with publicaly known user name and password and forget to chang it. Now CLI does not allow me to enter in the privillaged mode. Please help me out. Thanks

Dear Experts, I am very biggener to Cisco World. I am going to creat VLANs very 1st time therefore for test purpose I have following simple scnerio. I have created 2 VLANs , VLAN2 and VLAN3 on Cisco Catalyst 2960 series switch. Ports 1-12 is assigned to VLAN2 and Ports 13-24 are assiged to VLAN3. Now I have configured DHCP on Microsoft Server 2003 defining 2 scopes with following configurations. Scope 1 for VLAN 2--- Range is 172.16.0.17 to 172.16.0.30 with subnet mask=255.255.255.240 . Server IP address 172.16.0.17 ( Note: Address 172.16.0.17 is excluded from dhcp server Scope 1 and give to the MS server itself) Scope 2 for VLAN 3----Range is 172.16.0.33 to 172.16.0.46 with subnet mask=255.255.255.240 . Now in Cisco 2960 series switches, under Vlan 2 and Vlan 3, I have following configurations... interface Vlan2 ip address 172.16.0.30 255.255.255.240 ip helper-address 172.16.0.17 interface Vlan3 ip address 172.16.0.46 255.255.255.240 ip helper-address 172.16.0.17 Now the problem is when i connect a client computer to any port from 1-12, It gets correct IP address from Scope 1 but when I connect a computer to any port from 13-24, it does not get the ip address. Can anyone help me in this regard please. Further I want to do inter VLAN comunication as well for that purpose i Have an ISR 2900 series router. What further configuration i will have to do on router for inter vlan communication. Please help me out... Regards Shahzaib Khan

Hi Friends, I have some basic knowledge of making switch ports as 1 ethere channel. I just want to know something. I have 4 cisco 2960 switches to which many users are connected. No vlans are the only default vlan 1 is there. Now I want to make ether channel on switch 1 whcih has 24 fast etherenet ports. Can I make port 1- 8 as one ether channel which are connected to users or i can only make ethere channel of ports that are connectd to other switchs. If I can, how the other switchs will comnicate with the switch ports bundalled in the ether channel in switch 1. Please help me out.. Thanksss in advance.

Dear Friend, I have Cisco 2600 series Router which has only 32 MB flash memory. I tried to load IOS image in that but image size is 29 Mb in compressed form. The minimum i found is 5 MB in compressed form but it is missing so many commands. Can anybody tell me that in 32 MB flash, how can I load image which has almost all the commands. Thanks Best Regards Shahzaib Khan
