How to Monitor Switch Ports in Cisco Meraki Dashboard

Normal port states 

• Default Display Icon	Color Assist Icon	Explanation
  		Link operating at full 1Gbps (or 10Gbps on SFP+ ports)
  		Link operating at reduced speed/duplex (10 or 100Mbps)
  		Link disabled administratively
  		Link disconnected
  		Link has active PoE draw (802.3af or 802.3at)
  		Link has been detected as uplink to Internet path (Meraki Cloud uplink)
  		Link is disconnected, but port has active PoE draw (indicates potential cabling issue)

Moderate error states 

Default Display Icon	Color Assist Icon	Explanation
		Link in an erroneous state with one of the following error types: Speed Downshifted: problem causing for non-optimal link state (both the interface and connected device are advertising a faster link speed but a problem is causing the speed to downshift) PoE denied: port is waiting for power (may indicate that currently there is not enough available power for the port and connected device) Authentication failure: port not forwarding due to 802.1x authentication problem BPDU conflict: switch is seeing BPDUs from multiple sources on a full-duplex link High amount of L1 packet errors: port is sending or receiving a high amount (greater than 100 hits/hour or greater than 1% of traffic) of CRC align errors, Fragments, and/or Collisions

High-severity error states 

The following error types indicate a high-severity condition: 

Default Display Icon	Color Assist Icon	Explanation
		Link in an erroneous state with one of the following error types: PoE overload: connected device is consuming more power than the maximum limit configured or specified in the 802.3at/af standards Loop Inconsistent: loop guard is activated Very High amount of L1 packet errors: port is sending or receiving a very high amount (greater than 1000 hits/hour or greater than 10% of traffic) of CRC align errors, Fragments, and/or Collisions

Blocking symbol 

The blocking symbol can combine with any other port state above. It specifies that the port is in one of the following states: 

Configuration 

This section displays configuration details about the selected port. To modify the configuration, select Edit Configuration at the top of the section. 

The configuration details include: 

• Description: A configuration description (for example, Access port on VLAN20). 

• Link Negotiation: The current link negotiation state (Auto, 10Mbps Half, 10Mbps Full, 100Mbps Half, 100Mbps Full, 1 Gbps Full, 10Gbps Full). 

The RSTP field shows the port's RSTP state. Each port can be in one of these states: 

• Enabled – RSTP will be used when the port is connected. 

• Forwarding – RSTP is in use and the port forwards traffic. 

• Blocking – RSTP is in use and the port discards traffic, because it would introduce a routing loop. 

• Disabled – RSTP will not be used when the port is connected. 

Status 

This section displays information about the current port status: 

• Connectivity: Shows detailed information about the port connectivity state. The color of the connectivity bar varies depending on the link state. Use the legend in Figure 2. 

• Usage: The total usage on this switch port over the previous thirty seconds. 

• Traffic: The total traffic on this switch port, including broadcast traffic. Averaged over the previous thirty seconds. 

• LLDP: Shows detected LLDP client information for the selected port. This field contains a direct link to the detected client device(s). It also offers an option to display the raw LLDP information. 

Current clients 

This displays details about the currently connected client(s) behind the selected switch port. 

Packets 

This displays detailed packet information for the selected switch port. It includes the total, sent, received, and rate values for Total, Broadcast, and Multicast traffic. The table also displays counters for CRC align errors, fragments, collisions, and topology changes.
