3Com Switches 5500 – Quick Setup Guide!
Hello friends, the following commands are accepted by most Switches 3com and are quite useful. Many commands are taken directly from the manufacturer’s manual.
Setting the name of the Switch
[[5500G-EI] sysname SW_Core [SW_Core]
Vlans configuration
Creating a VLAN and putting a name
[Switch] vlan 3 [Switch-vlan] name
Creating a VLAN and placing a description
[Switch] vlan 3 [Switch-vlan] description
Creating a multiple VLANs at the same time
[ [Switch] vlan to 2 to 5
Deleting a vlan
[Switch] undo vlan 2
Showing that the VLANs that exist on the switch
[Switch] display vlan
Showing information for a particular VLAN (description, IP address, if any, port tagged and untagged)
[Switch] display vlan 2
Setting the IP to VLAN 2
[Switch] interface Vlan-interface 2 [Switch] -Vlan-Interface] ip address 192.168.100.1 255.255.255.0
Setting the default gateway
[Switch] ip route-static 0.0.0.0 0.0.0.0 192,168,100,254 (gateway IP)
Port Settings
Entering the configuration mode of a port
[Switch] gigabit-ethernet interface 1/0/4
Putting a description on the door
[Switch] gigabit-ethernet interface 1/0/4 [Switch-GigabitEthernet] description
Adding port to a vlan
Setting up the door
ACCESS door: Access port, used to connect hosts (stations, servers, etc.)
[Switch] gigabit-ethernet interface 1/0/4 [Switch-GigabitEthernet] port link-type access
TRUNK port: port that will allow more than one VLAN traffic through the door (using TAG (802.1q) Used as uplink port, the links between switches..
[Switch] gigabit-ethernet interface 1/0/5 [Switch-GigabitEthernet] port link-type trunk
Associating a door access to a vlan.
[Switch] gigabit-ethernet interface 1/0/4 [Switch-GigabitEthernet] port access vlan 5
Removing a VLAN an access port. The door will once again belong to VLAN 1 (default)
[Switch] gigabit-ethernet interface 1/0/4 [Switch-GigabitEthernet] undo port access vlan
Associating all VLANs the trunk port. Thus, all VLANs will pass through the port trunk
[Switch] gigabit-ethernet interface 1/0/5 [Switch-GigabitEthernet] port trunk permit vlan all
Copying settings from one port to another (vlan, spanningtree, speed etc.). Does not make a copy of the broadcast control settings
[Switch] copy configuration source gigabit-ethernet 1/0 / 1destination giggabit-ethernet 1/0/6
Copying settings from one port to multiple ports
[Switch] copy configuration source gigabit-ethernet 1/0 / 1destination giggabit-ethernet 1/0/6 to gigabit-ethernet 1/0/12
Setting the ADMIN user password .
Local-user admin service-type telnet terminal level 3 password Cipher s3nha
Removing users and default MANAGER MONITOR
[Switch] undo site-user manager [Switch] undo site-user monitor
Configuring and enabling SNMP management with communities and s1ro s1rw
[Switch] snmp-agent community read s1ro [Switch] snmp-agent community write s1rw
Removing the default communities PUBLIC and PRIVATE
[Switch] undo snmp-agent community write private [Switch] undo snmp-agent community read public
Enabling the spanning tree protocol (is already enabled by default)
[Switch] stp enable
Setting the version of the rapid spanning tree protocol
[Switch] stp mode rstp
Configuring the switch as the root bridge of the spanning tree primary
The stp root primary command automatically configures the value of the Bridge Priority to 0 (zero)
[Switch] stp root primaryor [Switch] stp priority 0
Configuring the switch as root secondary bridge spanning tree
The stp root command automatically configures the secondary value of the Bridge Priority for 4096
[Switch] stp root secondary
or
[Switch] stp priority 4096
Creating a link aggregation between two switches. Do not forget to perform these procedures on both switches. In this example are the ports used 1/0/25 and 1/0/26 of the two switches.
link-aggregation group 1 mode static #GigabitEthernet 1/0/25 interface undo shutdown port link-aggregation group 1 #GigabitEthernet 1/0/26 interface undo shutdown port link-aggregation group 1
