Do I need to configure my switch?
Most switches used by small businesses and home offices typically require no configuration — they’re “plug and play.” However, it’s important to remember that plug and play doesn’t always work. In addition, these switches certainly don’t offer any troubleshooting, logging, security, or manageability.
What do you need to do before you can configure a switch?
- Step 1: Inspect your hardware. Check the model number of your shiny new switch.
- Step 2: Set up management IP.
- Step 3: Check VTP revision number.
- Step 4: Configure access ports.
- Step 5: Configure trunk ports.
- Step 6: Configure access ports.
- Step 7: Set up VTY line config.
Do Cisco switches support LACP?
LACP allows Cisco switches to manage Ethernet channels between switches that conform the 802.3ad protocol. You can configure maximum 16 ports to form a channel depending on IOS version and platform.
How do I bring up a console switch?
Follow these steps to manage the switch via console port:
- Step 1 Connecting the PC to the Switch. Connect your PC to the console port of the switch with a console cable as the following figure shows.
- Step 2 Installing PuTTY on the PC.
- Step 3 Launching PuTTY and Configuring the PuTTY Session.
- Step 4 Launching the CLI.
How to put a port in LACP mode?
LACP mode that places a port into an active negotiating state, in which the port initiates negotiations with other ports by sending LACP packets. To configure port as an LACP active mode: switch# configure terminal. switch (config)# interface fastethernet 0/1. switch (config-if)# channel-group 5 mode active.
What happens when LACP is enabled between two switches?
At the moment LACP enabled between the two switches, they will send LACPDUs (LACP data units) to each other. After receiving LACPDUs from each other, the two switches will determine which side’s system priority is higher.
How to establish redundancy with LACP Trunking Network?
Scenario A: Switch 1 has ports 1+2 trunked together via LACP. They are plugged into Switch 2 ports 1+2. Scenario B: Switch 1 has ports 1+2 trunked together without LACP. They are plugged into Switch 2 Ports 1+2. In Scenario B I can unplug one of the patch cables and the switches will still be linked, establishing redundancy.
How are two LACP configured devices exchange LACPDUs?
Two LACP configured devices exchange LACPDUs to form a link aggregation group (LAG). A device is configurable as an active or passive participant. In active mode, the device initiates DUs irrespective of the partner state; passive mode devices respond only to the incoming DUs sent by the partner device.
