Switch Port View

Locating a specific port for further details and statistics is easy and can be done by viewing the visual port detail view after selecting a switch.

Port Overview

The Switch Ports section shows a basic view of the status on all switch ports. The interface displays a lot of information including a visual representation of each port's status.

 

The visual port state displays information in the following ways:

Display Icon
Explanation
Link operating at full 1Gbe (or 10Gbe 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 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

High amount of L1 packet errors: port is sending or receiving a high amount (greater than 1% of traffic) of CRC align errors, Fragments, and/or Collisions

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

Very High amount of L1 packet errors: port is sending or receiving a very high amount (greater than 10% of traffic) of CRC align errors, Fragments, and/or Collisions

The blocking symbol can be combined with any other port states above.

The blocking symbol specifies the port is in one of the following states:

STP discarding: port is in an STP discarding state

LACP disabled: LACP has disabled the port

The switch ports detailed view can also be expanded to show the following information:

Column
Description
Port # Specified port number on the switch
Type active port configuration type (access/trunk)
VLAN actively configured VLAN(s) and voice VLAN
Current Traffic (sent/received live ingress/egress traffic flow for the specified interface
RSTP state active RSTP port state (Enabled, Forwarding, Blocking)
PoE active PoE draw in Watts (advertised PoE in Watts)
LLDP detected LLDP client information including a direct link to the detected client device(s) for further detail
Link Link negotiation state
Status visual indication of the port's connection status over a 24-hr period (more detail is provided by hovering over this field)

By selecting a specific port, you can get more specific detail about that particular switch port.

Configuration

This section displays configuration details about the selected port. You can also very easily modify the selected port's configuration by selecting Edit Configuration from the top of this section.

Description

A configuration description (e.g. Access port on VLAN20). 

RSTP

The port's RSTP state (Each port can be in one of the following RSTP states: 

  • Enabled - RSTP will be used when the port is connected
  • Forwarding - RSTP is in use and the port is forwarding traffic
  • Blocking - RSTP is in use and the port is discarding traffic because it would introduce a routing loop
  • Disabled - RSTP will not be used when the port is connected

Link Negotiation

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

 

Status

This section displays information about the current port status, including:

Connectivity

This view shows detailed information about the port connectivity state. The color of this connectivity bar will vary depending on the link state. (Use the legend in figure 2 below).

Figure 2

Usage

This is the total usage on this switch port, over the previous thirty seconds.

Traffic

This is the total traffic on this switch port, including broadcast traffic, averaged over the previous thirty seconds.

LLDP

This shows details about the detected LLDP client information on the selected switch port. This field contains a direct link to the detected client device(s) for further detail, as well as an option to display the raw LLDP information. Note: Other networking devices can advertise their identities using LLDP. The format and content varies greatly.

Current Clients

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

Packets

This section displays detailed packet information in relation to the selected switch port, including the total, sent, received and rate values for Total, Broadcast and Multicast traffic. This table will also display counters for CRC align errors, Fragments and Collisions. An example is provided in figure 3 below.
