1 Connect a terminal or workstation
running terminal emulation software to
the console port, as detailed in “Using
the Console Interface”.
2 At your terminal, press [Return] one
or more times until you see the login
prompt.
3 At the login prompt, enter your user
name and password. The user name
is not case-sensitive. The password is
case-sensitive.Ensurethatyouhave
entered a user name and password with
administrator privileges.
 Ifyouarelogginginforthersttime,
use the default user name admin to log
in with administrator privileges. For
example:
login: admin
Administrator capabilities enable you to
access all switch functions. The default
user names have no passwords assigned.
If you have been assigned a user name
and password with administrator
privileges, enter them at the login
prompt.
4 At the password prompt, enter the
password and press [Return].
When you have successfully logged in to
the switch, the command line prompt
displays the name of the switch.
5 Assign an IP address and subnetwork
mask for the default VLAN by using the
following command:
 congure{vlan}<vlan_name>ipaddress
[<ipaddress>{<ipNetmask>}|ipv6-
linklocal|{eui64}<ipv6_address_mask>]
For example:
 congurevlandefaultipaddress
123.45.67.8255.255.255.0
The changes take effect immediately.
 NOTE:Asageneralrule,when
conguringanyIPaddressesforthe
switch, you can express a subnet mask by
using dotted decimal notation or by using
classless inter domain routing notation
(CIDR). CIDR uses a forward slash plus
the number of bits in the subnet mask.
Using CIDR notation, the command
identical to the previous
 Exampleis:
 congurevlandefaultipaddress
123.45.67.8/24

 congureiprouteadddefault<gateway>

For example:
 congureiprouteadddefault123.45.67.1

 disableigmpsnooping{forward-

Enable Jumbo packets and set the
size to the Max
To enable jumbo frame support, enable
jumbo frames on the desired ports. To set
the maximum jumbo frame size, use the
following command:
 congurejumbo-frame-size<framesize>
The jumbo frame size range is 1523 to
9216.Thisvaluedescribesthemaximum
size of the frame in transit (on the wire),
and includes 4 bytes of CRC plus another 4
bytes if 802.1Q tagging is being used.
