SDM (Switch Database Manager)

 

SDM Stands for Switch Database Manager.

Multi-Layer Switches provides switching as well as routing functions. SDM is used to manage the memory usage on multi-layer switches (Memory should be assigned for routing or switching).

If you want to use a multi-layer switch for routing function, there is no need to assign memory for storing MAC Addresses.

If you want to use a multi-layer switch for the switching function, there is no need to assign memory for storing routing table entries. In simple terms, SDM allows managing the size of the tables used by multi-layer switches.

There are 4 types of templates used in SDM

1) Default

• This is the default mode used by all the switches.

• This is the default mode used by all the switches.

• The default temple give balance to all functions.

• It support both routing and switching.

• No. of MAC Addresses supported in this template is 6K.

• No. of routes supported in this template is 8k.

2) Routing

• This SDM Template is used when you want to use multi-layer switch mostly for routing functions.

• Most of the memory is allocated to routing function.

• No. of MAC Addresses supported in this template is 3k.

• No. of routes supported in this template is 11k.

3) VLAN

• This SDM Template is used when you don't want routing capabilities on the multi-layer switch.

• Most of the memory is allocated to switching function.

 • No. of MAC Addresses supported in this template is 12k.

• No. of routes supported in this template is 0.

4) Access

• This access Template is used when you want to create more ACLS on a Multi-layer switch.

• Most of the memory is allocated for creating Access Control List.

• No. of MAC Addresses supported in this template is 4k.

 • No. of routes supported in this template is 6k.

CSST COURSE 1.0

Q1. WHAT IS A ADDRESSING. Network addressing is like a two-part delivery system:   Logical Addressing (IP): This is like your permanent address (e.g., 192.168.1.1) that lets data find your device anywhere on the internet. Physical Addressing (MAC): Think of this as a unique ID for your device's network card (AA:BB:CC:DD:EE:FF) used for local delivery within your network. Q2. WHAT IS A PACKET AND FRAME . Packets: Layer: Network Layer (Layer 3) Content: The actual data you want to send, like an email, a video, or website information. Addressing: Contains logical addresses (IP addresses) to identify the sender and receiver on the network. Size: Can vary depending on the data type, but generally larger than frames. Travels across networks: Packets can travel across different networks, like the internet, as they are routed based on IP addresses. Frames: Layer: Data Link Layer (Layer 2) Content: The packet wrapped with additional information for local deliver...

DOS AND DDOS ATTACK

A Dos (Denial-Of-Service) Attack and A DDOS (Distributed Denial-Of-Service) Attack Are Both Attempts to Make a Computer System or Network Resource Unavailable to Legitimate Users. However, They Differ in How They Achieve This: Dos Attack: Imagine A Single Person Throwing Rocks at A Castle Gate. A This Person Represents the Attacker, And the Rocks Represent the Malicious Traffic. The Castle Gate Represents the Target System or Network Resource. The Attacker Keeps Throwing Rocks, Trying to Overwhelm the Gate's Defenses and Gain Entry. Dos Attacks Are Typically Launched from A Single System. They Can Be Effective Against Small Systems or Networks, But Larger Systems Can Often Withstand Them. DDos Attack: Imagine An Army Throwing Rocks at A Castle Gate. This Army Represents the Attacker, And the Rocks Represent the Malicious Traffic. The Castle Gate Represents the Target System or Network Resource. The Attackers Coordinate Their Attack, Throwing Rocks from Multiple Directions at Once. ...
