byte (using SHA-1 key folding). Authenticated key is in the range of 16 byte (using md5 key folding) or 24 byte

(using SHA-1 key folding).

Privkey is encrpted key. Unencypted key ranes from 16 byte, and encrypted key ranes from 16 byte.

Keyword encrypt-authpassword, encrypt-authkey, encrypt-privpassword, encrypt-privkey are only used in

command line created by compile to prevent leaking plain text password and key. When deconfiguring SNMP, user

cannot use above keywords.

For example:

! Add user “user1” for local engine to group “grp1”, and configure this user not to use authentication and

encryption.

QTECH(config)# snmp-server user user1 grp1

! Add user “user2” for local engine to group “grp2”, and configure this user to use md5 authentication and

non-encryption with the auth-password to be 1234

QTECH(config)# snmp-server user user2 grp2 auth md5 auth-password 1234

! Add user “user3” for local engine to group “grp3”, and configure this user to use md5 authentication and des

encryption with the auth-password to be 1234 and privpassword to be 4321

QTECH(config)# snmp-server user user3 grp3 auth md5 auth-password 1234 priv des

priv-password 4321

2.10 System IP configuration

IP address means a unique address of 32 bits which is distributed to host in Internet. IP address consists of

network number and host number. The structure of IP address can make us easy to address in Internet. The ways to

obtain IP address are by DHCP (dynamic host configuration protocol), whose client can dynamically require to

configuration information to DHCP server, including: distributed IP address, netmask, default gateway; BOOTP (Ip

address configuration for statistic host) and manual operation by ipaddress command. Only one can be choosed to

obtain IP address.

2.10.1 Configure manage VLAN

Manage VLAN means only users in specified VLAN can communicate with switch. At most 26 managed vlan

can be configured. By default, VLAN with its id being 1 is included.

ipaddress vlan vlan-id

no ipaddress vlan vlan-id

Use these commands to add or delete managed VLAN. vlan-id ranges from 1to 4094. It must be existed

VLAN.

2.10.2 Configuration ip address by manual operation

Use ipaddress command in global configuration mode to configuration ip address, netmask, and gateway or

default gateway by manual operation:

ipaddress ip-address mask [ gateway ]

ip-address means system ip address. Mask means netmask. gateway:If only IP address and netmask are

configured, and gateway is not, the gateway will be default to be 0.

For example:

! Configure IP address to be 192.168.0.100, netmask to be 255.255.0.0.
