Routed ports on a multilayer switch function as traditional Layer 3 interfaces, allowing IP routing and enabling communication between different VLANs or subnets. They do not belong to any VLAN and are typically used for connecting to other routers or Layer 3 devices. Routed ports can be configured with an IP address and support routing protocols, making them integral for inter-network communication.
It combines switching and routing
Layer 3
It can work at multiple OSI layers at the same time.
It's a module included in the Catalyst Multilayer switches (eg: 5000,6000 series) to act as a 3rd layer device.Route Switch Module.
In some languages and programming environments, a case or switch statement is considered easier to read and maintain than an equivalent series of if-else statements, because it is more concise. However, when implemented with fall-through, switch statements are a frequent source of bugs among programmers new to the switch statement.
Statements doesn't have prototypes, functions do.
Control statements are statements that alter the flow of execution according to the evaluation of an expression (the condition). The C++ control statements are ifstatements, switch statements and the tertiary conditional operator, ?:.
A Switch statement can be considered as a series of if. else if. else statements. whatever condition is satisfied, the code block would get executed. if (cond 1) { } else if (cond 2) { } else if (cond 3) { } ...... } else if (cond N) { } else { } switch { case 1: .... case 2: .... .... case N: ... default: ... } Difference: In the if else blocks, if one condition is satisfied, all other blocks are ignored In Switch blocks, unless you have break statements inside each condition block, the subsequent blocks would not be ignored.
You have to include the two statements ...
I really think this is not possible.
As many as you like. Its unlimited. :)
Because it prevents the flow between cases.
