A single end device can use a port channel across two upstream switches. Cisco Nexus switches with vPC appear to downstream devices as if they are a single device. The other device can be a switch, a server, or any other networking device that supports the IEEE 802.3ad port channel. Cisco NX-OS software virtual port…

Cisco NX-OS load-balances traffic across all operational interfaces in a port channel by reducing part of the binary pattern formed from the addresses in the frame to a numerical value that selects one of the links in the channel. Traffic load balance hashing will depend on the traffic header. A binary format will be generated…

In the Ethernet infrastructure the STP achieves stable network, but it does not utilize the available physical connectivity in the best way, as some of the links between the same devices are put in blocking state, as to avoid network loops. And as it was already discussed, the goal of the STP is to achieve…

Rapid PVST+ provides for rapid recovery of connectivity following the failure of a network device, a switch port, or a LAN. It provides rapid convergence for edge ports. Rapid PVST+ is the IEEE 802.1w (RSTP) standard implemented per VLAN. A single instance of STP runs on each configured VLAN (if you do not manually disable…
