Cisco CATALYST 2960 - Configuring the NVRAM Buffer Size; The default NVRAM buffer size is 512 KB. In some cases, the configuration file might be too large to save to NVRAM. Typically, this occurs when you have many switches in a switch stack. You can configure the size of the NVRAM buffer to support larger configuration files. The new NVRAM buffer size is synced to all current and new member switches.

Appendix C Configuring the Switch with the CLI-Based Setup Program
Entering the Initial Configuration Information
Step 6 (Optional) Configure Simple Network Management Protocol (SNMP) by responding to the prompts.
You can also configure SNMP later through the CLI, the device manager, or the Network Assistant
application. To configure SNMP later, enter no.
Configure SNMP Network Management? [no]: no
Step 7 Enter the interface name (physical interface or VLAN name) of the interface that connects to the
management network, and press Return. For this release, always use vlan1 as that interface.
Enter interface name used to connect to the
management network from the above interface summary: vlan1
Step 8 Configure the interface by entering the switch IP address and subnet mask and pressing Return. The IP
address and subnet masks shown below are examples.
Configuring interface vlan1:
Configure IP on this interface? [yes]: yes
IP address for this interface: 10.4.120.106
Subnet mask for this interface [255.0.0.0]: 255.0.0.0
Step 9 Enter Y to configure the switch as the cluster command switch. Enter N to configure it as a member
switch or as a standalone switch.
If you enter N, the switch appears as a candidate switch in the Network Assistant GUI. You can
configure the switch as a command switch later through the CLI, the device manager, or the Network
Assistant application. To configure it later, enter no.
Would you like to enable as a cluster command switch? [yes/no]: no
You have now completed the initial configuration of the switch, and the switch displays its initial
configuration. This is an example of output that appears:
The following configuration command script was created:
hostname switch1
enable secret 5 $1$Ulq8$DlA/OiaEbl90WcBPd9cOn1
enable password enable_password
line vty 0 15
password terminal-password

!
no ip routing

end
Step 10 These choices appear:
[0] Go to the IOS command prompt without saving this config.
[1] Return back to the setup without saving this config.
