The Cisco C8200L-1N-4T router supports various Network Interface Modules (NIMs) to extend its connectivity options. Here are the key differences between the NIM-ES2-4 and the C-NIM-2T:
The Cisco C8200L-1N-4T router supports various Network Interface Modules (NIMs) to extend its connectivity options. Here are the key differences between the NIM-ES2-4 and the C-NIM-2T:
NIM-ES2-4
- Full Name : Network Interface Module - Enhanced Service Module (4-port)
- Ports : 4 Ethernet ports
- Type : Fixed 10/100/1000 Mbps Ethernet
- Functionality : Provides additional Ethernet interfaces for general connectivity. It does not include advanced features like MACsec (Media Access Control Security).
- Usage : Ideal for basic Ethernet connectivity and expanding the number of Ethernet ports available on the router.
C-NIM-2T
- Full Name : Cisco Catalyst Network Interface Module - 2-port 1GE SFP with MACsec
- Ports : 2 SFP (Small Form-factor Pluggable) ports, supporting 1 Gbps Ethernet
- Type : SFP, which allows for fiber or copper connections via SFP modules
- Functionality : Provides secure Ethernet connectivity with MACsec (Media Access Control Security), which encrypts data at the Layer 2 level.
- Usage : Suitable for environments requiring secure communication, such as sensitive data transmission over untrusted networks. It provides flexibility with the use of SFP modules to accommodate different types of media (fiber or copper).
Key Differences Summarized:
1. Port Type :
- NIM-ES2-4 : Fixed 10/100/1000 Mbps Ethernet ports.
- C-NIM-2T : 1 Gbps SFP ports (can support fiber or copper through SFP modules).
2. Port Count :
- NIM-ES2-4 : 4 Ethernet ports.
- C-NIM-2T : 2 SFP ports.
3. Advanced Features :
- NIM-ES2-4 : Does not support MACsec.
- C-NIM-2T : Supports MACsec for secure Layer 2 encryption.
4. Use Case :
- NIM-ES2-4 : General expansion of Ethernet ports for basic connectivity needs.
- C-NIM-2T : Secure, flexible connectivity with MACsec and SFP versatility.
When to Use Each Module:
- NIM-ES2-4 : If you need to expand the number of standard Ethernet ports on your router without the need for secure Layer 2 encryption.
- C-NIM-2T : If you require secure Ethernet connections with MACsec, or if you need the flexibility of using SFP modules for different types of connections (e.g., fiber for longer distances or copper for shorter runs).
Choosing between these modules depends on your specific network requirements, particularly regarding the need for security features like MACsec and the type of physical connections you plan to use.
