Power over Ethernet Capabilities of 48 Ports Expansion Module
The C9400-LC-48UX Cisco 48 Ports UPoe 10GE Expansion Module is a line card module designed for use with the Cisco Catalyst 9400 Series switches. This module supports Power over Ethernet (PoE) capabilities, specifically the Universal Power over Ethernet (UPoE) standard.
UPoE is an extension of the standard PoE technology and provides up to 60 watts of power per port, which is more than enough to power devices such as IP phones, wireless access points, and video cameras. The C9400-LC-48UX module can deliver UPoE to all 48 ports, providing a total power budget of up to 2,940 watts.
It is important to note that the C9400-LC-48UX module requires an external power supply to deliver UPoE to connected devices. The power supply must be capable of delivering the necessary power to support all connected devices. Additionally, the module supports the IEEE 802.3at PoE+ standard, which provides up to 30 watts of power per port.
Quality of Service (QoS) Features and Configuration
The Cisco C9400-LC-48UX is a 48-port expansion module that provides high-speed connectivity for network devices. It supports both Ethernet and PoE (Power over Ethernet) and can be used to expand the connectivity of a Cisco Catalyst 9400 Series Switch.
In terms of Quality of Service (QoS) features, the C9400-LC-48UX supports several QoS mechanisms to help ensure that network traffic is prioritized appropriately. These QoS mechanisms include:
- Classification: The C9400-LC-48UX supports classification based on Layer 2 and Layer 3 information, such as MAC addresses, IP addresses, and protocols. This allows network administrators to identify and prioritize different types of traffic.
- Policing: The C9400-LC-48UX can enforce policing policies to limit the amount of traffic that is sent or received by a particular device or group of devices.
- Shaping: The C9400-LC-48UX can shape traffic to ensure that it conforms to specific bandwidth limits.
- Marking: The C9400-LC-48UX supports the marking of packets based on QoS policies. This allows network administrators to mark packets as high, medium, or low priority based on their content.
- Queuing: The C9400-LC-48UX supports multiple queues per port, which can be used to prioritize different types of traffic. This allows network administrators to ensure that high-priority traffic is sent before lower-priority traffic.
In terms of configuration, the C9400-LC-48UX can be configured using Cisco IOS software. The following are the basic steps to configure QoS on the C9400-LC-48UX:
- Enable QoS on the switch using the “mls qos” command.
- Configure QoS policies using the “policy-map” command. These policies can be used to classify, mark, and prioritize traffic.
- Apply the QoS policies to the appropriate interfaces using the “service-policy” command.
- Verify the QoS configuration using the “show policy-map interface” command.
