Network Interfaces

A network interface is the interconnection between a device and a network. Monitoring interfaces provides real-time availability statistics and detailed analysis of data from switches, routers, firewalls, and other SNMP-enabled devices.

Where are network interfaces listed in Site24x7?

1. Log in to your Site24x7 account.
2. Navigate to Network > Network Interfaces.

To view the network interfaces corresponding to a particular network device:

1. Navigate to Network > Network Devices.
2. Click the device and select the Interfaces tab (In Figure 2, it is marked as "1").
3. Click the hamburger icon next to a network interface to suspend it, edit the display name, change the interface settings, and associate tags (In Figure 2, it is marked as "2").

How does the Network Interfaces page help me?

This page lists the state of interfaces as Down, Up, or Trouble based on the most recent poll. Network interfaces that have their admin and operation states as Down are also listed.

Operation state: The current running state.

Admin state: The configured state of an interface.

How do I change interface settings?

1. Go to Network > Network Interfaces.
2. Click the hamburger  icon near the interface whose bandwidth needs to be updated.

3. Select Change Interface Settings from the drop-down list.
4. Perform the following steps:
   • Interface list: Select the required interfaces from the drop-down list.
   • Traffic counter: Select a counter based on your specific needs.
   • Out speed: Enter the out speed in Mbps.
   • In speed: Enter the in speed in Mbps.
5. Click Save.

How are network interfaces organized?

Tags are unique labels that allow you to assign custom metadata to your monitors for better classification and organization. You can also assign unique colors to each tag to easily identify and sort them.

Network interfaces are enabled to support tags, which can be viewed by clicking on the interface tab inside the network device's dashboard. You can associate predefined tags or create new ones; aside from that, you can also filter your network interfaces based on these tags in the Network Interfaces view.

What is the NOC view?

The NOC view for network interfaces displays all the network interfaces as color-coded tiles. Click the  icon near Quick Help on the Network Interfaces page for the NOC view. Statuses are displayed as green for Up, red for Down, and yellow for Trouble, and you can filter the view based on these statuses. Every tile displays the interface name, the corresponding device name in brackets, and the reason behind the status.

How can I configure thresholds?

You can configure thresholds for your network interfaces so that you receive alerts should any anomalies be detected. You can set thresholds for attributes like in and out traffic, Rx and Tx utilization, errors, and discards.

How do I activate or suspend interfaces in bulk?

You can activate or suspend interfaces in bulk from the Settings tab.

1. Navigate to Network > Settings > Bulk Activate/Suspend Interfaces.
2. Select the required Action—Activate or Suspend from the drop-down menu.
3. You can set multiple conditions. Hence choose the required condition operators—AND or OR.
4. Interfaces can be chosen in bulk based on their Device, Operational State, Status, Type, and Name.
5. Click Activate or Suspend.

How do I identify the top performing network interfaces?

Keep yourself updated about your network's health using Network Health Dashboard. This dashboard displays the top 10 network interfaces under each of the following categories: out traffic, in traffic, transmitting bandwidth utilization, receiving bandwidth utilization, out errors, in errors, out discards, and in discards.
