How do I assign a VLAN to a switch?
First, VLAN support needs to be enabled on the switch if it is not already:
- Choose Switch configuration.
- Choose Advanced Features.
- Choose VLAN Menu…
- Choose VLAN Support.
- Set Enable VLANs to Yes if it is not already, and choose a number of VLANs.
- Restart the switch to apply the changes.
How do you edit a VLAN?
To access VLAN database configuration mode, enter the vlan database privileged EXEC command. Then enter the vlan command with a new VLAN ID to create a VLAN, or enter an existing VLAN ID to modify the VLAN. You can use the default VLAN configuration (Table 12-2) or enter multiple commands to configure the VLAN.
How do I test a port on a switch?
At the lowest level, I would start by just plugging a computer into each port, one at a time and see if you get a link light. Next, plug two computers into different ports on the switch, with static IP addresses and see if they can ping each other. Move one of them to a different port and see if the pings continue.
What is TDR test in Cisco switch?
The Time Domain Reflectometer (TDR) feature allows you to determine if a cable is OPEN or SHORT when it is at fault.
Do all VLANs need an IP address?
As each VLAN is a different network, they need their own address subnet (IPv4 and IPv6). The Campus Core switch will route between each VLAN (so called L3-switch: an ethernet switch which has some L3 routing capability). These IP addresses are also documented in the master IP address plan.
Do I need to assign an IP to a VLAN?
NOTE: If multiple VLANs are configured, then each VLAN can have its own IP address. This is because each VLAN operates as a separate broadcast domain and requires a unique IP address and subnet mask. A default gateway (IP) address for the switch is optional, but recommended.
How do I know if my switch port is working?
Check for blinking green lights above the “WAN” and “LAN 1” ports on the Ethernet switch. A blinking green light represents an active connection. Open a Web browser on your laptop to confirm that the connection is active.
How do I run a TDR test?
- To start the TDR test, perform this task: Procedure.
- Purpose. Command or Action.
- Starts the TDR test. test cable-diagnostics tdr {interface {
- interface-number }}
- Displays the TDR test counter information. show cable-diagnostics tdr {interface.
- interface-number}
How does a TDR work?
A TDR works like radar. A fast rise time pulse is injected into the cable system at one end (near end). As the pulse travels down the cable, any change in the characteristic impedance (impedance discontinuities) will cause some of the incident signal to be reflected back towards the source.
