Cisco Nexus Spanning Tree Port Priority

Cisco Nexus Spanning Tree Port Priority. Port 257 (ethernet2/1) of vlan0001 is broken (port type inconsistent) port path cost 4, port priority 128, port identifier 128.257. This section describes the specific functions that are common to all spanning tree protocols.

Even if you had the highest bridge priority in the secondary, your vpc primary would forward bpdus in vpc domain. The root bridge may be in the data centre causing some traffic to cross the dci links. You can configure the port type either globally or per interface.

By Default, All Cisco Switches Has A Bridge Priority (Switch Priority) Value Of 32,768.

So some safeguard is needed. Port cost and port priority. The default spanning tree port type is normal.

This Bridge Is The Root.

The root bridge may be in the data centre causing some traffic to cross the dci links. Port 257 (ethernet2/1) of vlan0001 is broken (port type inconsistent) port path cost 4, port priority 128, port identifier 128.257. Configures the port priority as follows:

Switchport trunk allowed vlan 8,62,120,124. Imagine if you had one large domain. This section describes the specific functions that are common to all spanning tree protocols.

This Is The Command That Decodes That Number To A Port:

Designated root has priority 32769, address fa16.3efa.7a5c. If the switch does not become the root, an error results. The cisco proprietary spanning tree protocols, pvst+ and mistp, are based on the ieee 802.1d stp.

Normally, A Port Id Is Denoted In Hexadecimals Similar As 0X8015, Which Is Equivalant To 128.21 In Decimals, Where The First Part Is The Default Port Priority Number And Second Part Is The Switch Interface Identifier.

Having the same bridge priority is not a requirement to maintain vpc consistency. Default port costs are taken from the bandwidth of the interface, as follows: Every bridge (switch) participating in a spanning tree protocol network is assigned with a numerical value called bridge priority (switch priority) value.
