A port channel does a couple of things: Increases the available bandwidth between two devices. Creates one logical path out of multiple physical paths. Since Spanning Tree Protocol (STP) runs on the logical link and not the physical links, all of the physical links can be in a forwarding state.

Does port channel increase bandwidth?

A port channel does a couple of things: Increases the available bandwidth between two devices. Creates one logical path out of multiple physical paths. Since Spanning Tree Protocol (STP) runs on the logical link and not the physical links, all of the physical links can be in a forwarding state.

What is the MTU value for Ethernet channel?

1,500 bytes
Ethernet MTU The standard size MTU for Ethernet is 1,500 bytes. This does not include the Ethernet header of 18 or 20 bytes, and is the theoretical maximum amount of data that can be transmitted by the physical link. The MTU of any higher-level protocols must fit within this MTU.

How do I change the MTU on a Cisco interface?

An account on Cisco.com is not required. The default maximum transmission unit (MTU) size for frames received and transmitted on all interfaces is 1500 bytes. You can increase the MTU size for all interfaces operating at 10 or 100 Mb/s by using the system mtu global configuration command.

Can you span a port channel?

You can configure the source channels for a SPAN session. These ports can be port channels, SAN port channels, VLANs, and VSANs.

What is the difference between port channel and channel group?

A channel group is a collection of Ethernet interfaces on a single switch. A port channel interface is a virtual interface that serves a corresponding channel group and connects to a compatible interface on another switch to form a port channel.

How many ports can be in a port channel?

eight
A single logical interface is created called a port-channel. On the Cisco Catalyst switches we can aggregate up to eight 10/100 ports together creating a port-channel with 800 Mbps bandwidth (literature may indicate 1600 Mbps as the bundle has full-duplex operation).

What is the difference between MTU and IP MTU?

The main difference is interface MTU defined max packet size supported by an interface, while IP MTU is used to set MTU size of IP PACKET.

What is the difference between SPAN and Rspan?

When you use a destination interface on the same switch as your switch we call it SPAN, when the destination is a remote interface on another switch we call it RSPAN (Remote SPAN). When using RSPAN you need to use a VLAN for your RSPAN traffic so that traffic can travel from the source switch to the destination switch.

How do I setup port mirroring?

Click Add Port Mirror for each port mirror that you want to configure.

  1. Select a Monitor Port from the available list.
  2. Select a Mirroring port from the available list.
  3. Select one of the available options from the Traffic Direction list to indicate the monitoring direction of the packets.

How do I configure per-port MTU for a port channel?

Members of a port channel cannot be configured with Per-Port MTU, they derive their MTU from the port-channel MTU configuration. Per-Port MTU is not supported on sub interfaces and port-channel sub interfaces. You can configure the MTU size for all interfaces on a device at the same time using the system mtu command.

What is per-port MTU in Cisco IOS XE?

Starting with Cisco IOS XE 17.1.1, you can configure Per-Port MTU. Per-Port MTU will support port level and port channel level MTU configuration. With Per-Port MTU you can set different MTU values for different interfaces as well as different port channel interfaces.

What is the difference between per-port MTU and protocol-specific MTU?

Once the Per-Port MTU value has been configured on a port, the protocol-specific MTU for that port is also changed to the Per-Port MTU value. When Per-Port MTU is configured on a port, you can still configure protocol-specific MTU on the interface in the range from 256 to Per-Port MTU value.

How do I configure MTU size for all interfaces on a device?

You can configure the MTU size for all interfaces on a device at the same time using the system mtu command. The default maximum transmission unit (MTU) size for frames received and transmitted on all interfaces is 1500 bytes. The system mtu command is a global command and does not allow MTU to be configured at a port level.
