Is Cisco 3750X Layer 3?

The Cisco Catalyst 3750X-48T-S Layer 3 Switch with StackWise Plus technology provides scalability, ease of management and investment protection for the evolving business needs.

How do I change the priority of a switch?

How do users change the priority value? From the global configuration mode, issue the command switch stack-member-number priority new-priority-value. From the Bootloader switch: prompt, issue the command set SWITCH_PRIORITY new-priority-value.

How do you provision a switch?

For adding a switch to the stack follow these steps:

  1. Step 1) On the new switch give the global command: switch stack-member-number provision type.
  2. switch 3 provision ws3750g-24t.
  3. Step 2) Power off the new stack member.
  4. Step 3) Connect the new member to the Cisco stack using the stacking cables, 1 loop at a time.

How do I configure a switch stack?

Use the global configuration command switch stack-member-number priority new-priority-number to set a stack member to a higher member priority value….Add a stack member.

  1. Power off the new switch.
  2. Through their stacking ports, connect the new switch to a powered-on switch stack.
  3. Power on the new switch.

Can a switch have priority 0?

Setting value to 0 (spanning-tree priority 0) sets the root bridge permanently so that it won’t ever change without you wanting it. If you have 2 core switches, set the other one to priority 1 so that if the main core fails the whole network will switch to the other one.

How is the root port on a switch determined?

When determining the root port on a switch, the switch compares the path costs on all switch ports participating in the spanning tree. The switch port with the lowest overall path cost to the root bridge is automatically assigned the root port role because it is closest to the root bridge.

What is a provisioned switch?

If a switch that previously joined a stack is removed, the port numbers remain in the running-configuration, and the missing switch is shown as Provisioned. The Provisioned state might be caused by a switch that is no longer connected to the stack or be the result of manually pre-provisioning the related ports.

How do I remove a stack from a switch?

Complete these steps in order to remove a switch: Power off the new stack member to be removed….Resolution

  1. Issue the switch stack-member-number provision type command.
  2. Power off the new stack member.
  3. Reconnect to the existing switch stack through the StackWise ports.
  4. Power on the new stack member.

What are the benefits of switch stacking?

Benefits of the Switch Stacking

  • It reduces the management overhead.
  • By reducing the required number of switches, it also reduces the cost of the network.
  • It allows us to add or remove switches at any time without disrupting the running network or affecting its performance.

How do you identify a switch in a stack?

A switch stack is identified in the network by its bridge ID and, if the switch stack is operating as a Layer 3 device, its router MAC address. The bridge ID and router MAC address are determined by the MAC address of the stack master.

What is STP Bpdu guard?

BPDU Guard feature is used to protect the Layer 2 Spanning Tree Protocol (STP) Topology from BPDU related attacks. When a BPDU Guard enabled port receive BPDU from the connected device, BPDU Guard disables the port and the port state is changed to Errdisable state.

What can I do to see Packet Trace with 3750 switch?

The packets remain in the same VLAN, so ‘debug ip packet’ is not an option I suppose as they are not routed by the switch. I tried to use a policy map with ACLs but the statistics with ‘show policy-map int INT’ don’t show any matches. What can I do to see those packets? 07-11-2011 05:19 AM 07-11-2011 05:19 AM

Are there Cisco 3850 and 3750 layer 3 switches?

We are using Layer 3 Switches as Cisco 3850 and Cisco 3750, but they’re not available in PT, do you know a way to emulate them or upload them to my PT? Is it possible to stack them? Also, we have a 24 port layer 2 switch with 2 Fiber ports, (we’re on two different networks so we needs at least 24 ports).

How to configure intervlan routing with Cisco Catalyst 3750 / 3560?

This document explains how to configure interVLAN routing with Cisco Catalyst 3750/3560/3550 series switches. The document provides a sample configuration for interVLAN routing with a Catalyst 3550 series switch that runs enhanced multilayer image (EMI) software in a typical network scenario.

Where to find a span on a 3750 switch?

07-11-2011 05:19 AM If the two networked devices (or even one of them) was connected to the switch, you could use a SPAN on the port (s) connected to the device (s). If traffic between the two networked devices passed through the switch, you could configure a SPAN on the ingress trunk port and filter the VLAN of interest.
