Description
High Availability Features
The Cisco Nexus 3172TQ is a high-performance Ethernet switch designed for data center environments that require high availability, low latency, and high throughput. Some of the high availability features of the N3K-C3172TQ-ZV Cisco Nexus 3172TQ switch are:
- Redundant power supplies: The switch comes with two power supply units (PSUs) that can operate in a redundant configuration to ensure uninterrupted power supply in case of a PSU failure.
- Hot-swappable fans: The switch has four hot-swappable fans that can be replaced while the switch is running, which ensures continuous airflow and cooling even during fan failures.
- Virtual PortChannels (vPC): The Nexus 3172TQ supports vPC, which is a Cisco technology that enables the creation of a virtual link between two switches to provide a loop-free, redundant, and scalable network architecture.
- Graceful restart: This feature allows the switch to restart without disrupting the traffic flow. The switch maintains the state of the routing protocol and reconverges the routing tables quickly after the restart.
- Non-Stop Forwarding (NSF): NSF is a feature that allows the switch to continue forwarding traffic during a supervisor engine switchover, which minimizes the downtime.
- Bidirectional Forwarding Detection (BFD): BFD is a protocol that detects faults in the path between two switches, and it can quickly notify the switches to re-converge the routing tables.
- In-Service Software Upgrades (ISSU): This feature allows for the upgrading of the switch’s software while the switch is still operational. The upgrade process can be done without disrupting the traffic flow or causing any downtime.
Quality of Service (QoS) Configuration
Quality of Service (QoS) is an important aspect of networking that allows network administrators to prioritize network traffic based on different parameters such as bandwidth, latency, jitter, and packet loss. In order to configure QoS on the N3K-C3172TQ-ZV Cisco Nexus 3172TQ 48 Ports Ethernet Switch, the following steps can be followed:
- Identify the traffic that needs to be prioritized based on the requirements of the network. This could include critical applications such as voice or video traffic, as well as data traffic that requires low latency or high bandwidth.
- Configure the switch to classify the traffic using different methods such as access control lists (ACLs), Differentiated Services (DiffServ), or Class-Based Quality of Service (CBQoS).
- Define the QoS policies for each class of traffic based on the desired priorities and bandwidth allocations. This could include setting minimum and maximum bandwidth limits, configuring queuing mechanisms such as Weighted Fair Queuing (WFQ) or Low Latency Queuing (LLQ), and defining drop policies for excess traffic.
- Verify the QoS configuration using monitoring tools such as the Cisco Nexus Data Broker or the Cisco Nexus Analytics Platform. This can help identify any issues or bottlenecks in the network and allow for fine-tuning of the QoS policies.
Power and Cooling Considerations
The N3K-C3172TQ-ZV Cisco Nexus 3172TQ 48 Ports Ethernet Switch is a high-performance switch designed for data center and enterprise applications. This switch has a number of power and cooling considerations that are important to understand.
Power Considerations:
- The N3K-C3172TQ-ZV switch has a maximum power consumption of 400W.
- The switch can be powered by either AC or DC power sources.
- The switch has two power supply units (PSUs) for redundancy.
- The switch supports power over Ethernet (PoE) and can provide up to 30W of power per port.
Cooling Considerations:
- The N3K-C3172TQ-ZV switch has a front-to-back airflow design, meaning that air is drawn in through the front of the switch and exhausted through the back.
- The switch has four hot-swappable fan modules for cooling.
- The fan modules are designed to provide N+1 redundancy, meaning that one fan module can fail without affecting the cooling of the switch.
