These commands have been tested on the 6400 and 6850 models but may also work on others.
Reset switch to factory defaults
Delete the boot.cfg file from the working and certified directories and then reload the switch
cd working
rm boot.cfg
cd ..
cd certified
rm boot.cfg
reload
After it reboots type either of the following commands to verify that you have a new config file.
show configuration snapshot
write terminalSave configuration
The first command will save the primary (working) config and the second will save the secondary (Certified) config.
write memory
copy working certified
If you have a stack with 2 or more switches then use the following command to synchronise the config across all slots
copy working certified flash-synchro
Verify the configuration and synchronisation status with the following command.
show running-directory
You should get the results below
Quote:CONFIGURATION STATUS
Running CMM : PRIMARY,
CMM Mode : MONO CMM,
Current CMM Slot : 1,
Running configuration : WORKING,
Certify/Restore Status : CERTIFIED
SYNCHRONIZATION STATUS

Create new VLAN with description. I’ll be using VLAN 10 for this example.
vlan 10 name "Guest"
Remove VLAN with:
no vlan 10
Assign switch ports 1 through 24 on slot 1 to VLAN 10 using the following command:
vlan 10 port default 1/1-24
for 802.1q (tagged) port use the following command:
vlan 10 802.1q 1/1
You can remove the VLAN port members with the following command:
no vlan 10 port default 1/1-24
no vlan 10 802.1q 1/1
To verify the VLAN 10 configuration, use:
show vlan 10
To verify that ports 1/1-24 were assigned to VLAN 10 use:
show vlan 10 portInterface Configuration
Show status of all ports:
show interfaces status
Show information about all ports:
show interfaces port
To show information about a specific port only (slot/port):
show interfaces 1/5
Make changes to an interface with the following commands. I’ll be using slot 1 and port 5 in my examples.
Disable auto negotiate (enable or disable):
interfaces 1/5 autoneg disable
Change duplex (full or half):
interfaces 1/5 duplex full
Change interface speed (10,100,1000):
interfaces 1/5 speed 100
Disable or enable a port (up or down):
interfaces 1/5 admin down
Label the ports with:
interfaces 1/5 alias "Specify name here"
Create a management interface
ip interface "mgnt_IP" address 192.168.0.10 mask 255.255.255.0 vlan 3
Verify with:
show ip interface
Remove interface with
no ip interface "mgnt_IP"Link Aggregation
Run the following command to create a LACP group for ports 19,20,21 and 22. In this example i’ll be using 2 as the ID, 4 as the size and 5 as the key
lacp linkagg 2 size 4 admin state enable
lacp linkagg 2 actor admin key 5
lacp agg 1/19 actor admin key 5
lacp agg 1/20 actor admin key 5
lacp agg 1/21 actor admin key 5
lacp agg 1/22 actor admin key 5
Now set the VLAN for the LACP group:
vlan 3 port default 2POE
Start or stop POE on slot 1 (Change slot number accordingly):
lanpower start 1
lanpower stop 1
Start or stop POE on a port (slot/port):
lanpower start 1/5
lanpower stop 1/5System services
The following services are available:
ftp, ssh, telnet, http, secure-http, udp-relay, snmp, all
Enable a service:
ip service ssh
Disable a service:
no ip service ssh
