What is the BPDU Guard plz…………….Give me the full information about the BPDU Guard and what is the role of the BPDU Guard?

A Bridge Protocol Data Unit (BPDU) is an information message transmitted over a neighborhood to distinguish circles in system topologies. A BPDU contains data with respect to ports, switches, port need and addresses.

BPDUs contain the data important to design and keep up spreading over tree topology. They are not sent by switches, but rather the data is utilized by changes to figure their own particular BPDUs for data passing.

Best Practices to empower BPDU Guard just on get to ports (get to ports prompt to end client gadgets) so that any end client gadgets on these ports that have BPDU Guard empowered are not ready to impact the Spanning-tree topology.

Configuring BPDU Guard

Taking after are the modes in which we can design BPDU Guard in switches

Interface mode

Spreading over tree bpduguard empower (Puts port in errdisable after accepting any bpdu).

Global mode

Traversing tree portfast bpduguard default (It empowers bpduguard on ports that have port-quick design, places port in errdisable after getting a bpdu).

Once BPDU Guard is empowered it will keep an eye open for any BPDU's entering the get to ports. The main gadgets which can dependably make and transmit BPDU's are switches.

By configuring the "BPDU Guard" highlight on the get to ports empowers the spreading over tree convention to close the port down in the occasion that is gets a BPDU.

How to configure BPDU Guard per interface at Interface Configuration Mode

Below are the configuration commands enable BPDU Guard for an interface.

OmniSecuSW1#configure terminal
OmniSecuSW1(config)#interface giga 0/0
OmniSecuSW1(config-if)#spanning-tree bpduguard enable
OmniSecuSW1(config-if)#exit
OmniSecuSW1(config)#exit
OmniSecuSW1#

Below are the configuration commands disable BPDU Guard for an interface.

OmniSecuSW1#configure terminal
OmniSecuSW1(config)#interface giga 0/0
OmniSecuSW1(config-if)#spanning-tree bpduguard disable
OmniSecuSW1(config-if)#exit
OmniSecuSW1(config)#exit
OmniSecuSW1#
