GigE Vision Control Protocol (GVCP) packets are always received by Wireshark because they are passed through the eBUS Universal Pro driver from the NIC manufacturer's driver, and up to the network stack. ... However, the performance improvements gained by using the eBUS Universal Pro driver are removed by doing so.

VRRP (Virtual Routing Redundancy Protocol) is a cluster solution where two or more Gaia-based Security Gateways work together as one Security Gateway. You can configure a VRRP cluster for high availability and/or load sharing. The Check Point VRRP implementation includes functionality called Monitored Circuit VRRP.

The native IPSec packet would have an IP protocol header-value of 50. Since 50 is neither UDP (17) or TCP (6), stupid NAT gateways will drop the packet rather than pass it. Secondly, since IPSec is neither TCP or UDP, it doesn't have a port-number.

Asynchronous Transfer Mode is a set of protocols used for computer networks. It is mostly used for Wide Area Networks (WAN). It splits the data, and encodes it into packets of a fixed size. Each packet can be routed differently, along virtual paths set up in the network.

In control plane terms, HSRP with vPC is active/passive. This is because only the primary switch responds to ARP requests. ... In a non-vPC deployment, the active HSRP router will have a G flag (Gateway) listed. When a vPC enabled Nexus uses HSRP, both sides get the G flag, allowing both sides to forward traffic.
