What are redundant switches?
Redundancy Switching. Fundamentally, a redundancy switch has a 2×1 (1×2) arrangement. Automated redundancy switching is specifically designed to connect to both the primary and secondary equipment, and if there is a failure in the “primary” equipment, the backup is switched in.
Is router a load balancer?
A load balancing router, sometimes referred to as a failover router, will attempt to route internet traffic across two or more broadband connections in the most optimal way. This makes it possible to deliver a better experience to broadband users who are simultaneously accessing internet applications or files.
What do you need to know about EtherChannel load balancing?
EtherChannel load balancing can use MAC addresses, IP addresses, or Layer 4 port numbers with a Policy Feature Card 2 (PFC2) and either source mode, destination mode, or both. The mode you select applies to all EtherChannels that you configure on the switch. Use the option that provides the greatest variety in your configuration.
How many Ethernet interfaces can a catalyst 2950 switch support?
The Catalyst 2950/2955 series switch can support up to eight compatibly configured Ethernet interfaces in an EtherChannel. The EtherChannel can provide full-duplex bandwidth up to 800 Mbps (Fast EtherChannel) or 2 Gbps (Gigabit EtherChannel) between your switch and another switch or host.
How does Cisco’s hot standby Router Protocol work?
Hot Standby Router Protocol (HSRP) Cisco developed the proprietary Hot Standby Router Protocol (HSRP)to allow multiple routers or multilayer switches to masquerade as a single gateway. This is accomplished by assigning a virtual IP and MAC address to all routers participating in an HSRP group.
How many etherchannels can a Catalyst 4500 switch support?
A Catalyst 4500/4000 series switch with Cisco IOS Software (Supervisor Engine II+ and later) supports a maximum of 64 EtherChannels. You can form an EtherChannel with up to eight compatibly configured Ethernet interfaces on any module and across modules.
