Parameter

Meaning

 

 

 

 

Port Disabled

The number of BPDUs discarded because the port that the

 

 

BPDU was received on was disabled.

 

 

 

 

Invalid Protocol

The number of STP packets that had an invalid Protocol

 

 

Identifier field or invalid Protocol Version Identifier field.

 

 

 

 

Invalid Type

The number of STP packets that had an invalid Type field.

 

 

 

 

Invalid Message Age

The number of STP packets that had an invalid message

 

 

age.

 

 

 

 

Config BPDU length

The number of Configuration BPDUs that had an incorrect

 

 

length.

 

 

 

 

TCN BPDU length

The number of Topology Change Notification BPDUs that

 

 

had an incorrect length.

 

 

 

If necessary, all the STP configuration that users have created on the switch can be removed, so that all STPs except the default STP are destroyed, and all other defaults are restored, using the command:

PURGE STP

The PURGE STP command should be used with caution, and generally only before major reconfiguration of the switch, as it removes all STP configuration entered on the switch.

Interfaces to Layer 3 Protocols

Interfaces can be configured to VLANs for IP, IPX and Appletalk routing protocols in the same way that other interfaces are created for other interface types. Concatenate VLAN with the VID of the VLAN giving VLANn, for instance:

INTERFACE=VLAN3

IGMP Snooping

IGMP (Internet Group Management Protocol) is used by IP hosts to report their multicast group memberships to routers and switches. IP hosts join a multicast group to receive broadcast messages directed to the multicast group address. IGMP is an IP-based protocol and uses IP addresses to identify both the multicast groups and the host members. For a VLAN-aware devices, this means multicast group membership is on a per-VLAN basis. If at least one port in the VLAN is a member of a multicast group, by default multicast packets will be flooded onto all ports in the VLAN.

IGMP snooping enables the switch to forward multicast traffic intelligently on the switch. The switch listens to IGMP membership reports, queries and leave messages to identify the switch ports that are members of multicast groups.

Multicast traffic will only be forwarded to ports identified as members of the specific multicast group.

This provides businesses with the necessary tools to manage and direct network traffic efficiently. The switch includes support for VLAN (Virtual Local Area Network) technology, which allows for the segmentation of network traffic, enhancing both security and performance. With VLANs, organizations can isolate critical workloads and improve network management while ensuring that sensitive information is protected from unauthorized access.

Another key characteristic of the C613-02013-00 is its extensive support for Power over Ethernet (PoE). This feature enables the switch to deliver electrical power along with data over standard Ethernet cabling. This is particularly beneficial for powering devices such as IP cameras, wireless access points, and VoIP phones, reducing the need for additional power supply infrastructure. With PoE capabilities, the switch simplifies installation and enhances flexibility in deploying network devices.

The C613-02013-00 also boasts advanced network management features, including support for SNMP (Simple Network Management Protocol) for efficient monitoring and troubleshooting. This ensures that network administrators can maintain optimal performance and quickly address any issues that arise. Additionally, the switch supports network redundancy features like Rapid Spanning Tree Protocol (RSTP), which helps to prevent network loops and minimizes downtime.

In terms of physical characteristics, the C613-02013-00 is designed for durability and ease of deployment in various environments. Its compact form factor allows for effective space utilization in data centers and network closets. Moreover, it features a fanless design, making it suitable for deployment in noise-sensitive environments such as offices and classrooms.

In summary, the Allied Telesis C613-02013-00 is a robust network switch offering advanced features such as Layer 2 switching, PoE support, and comprehensive network management capabilities. Its design and performance make it an excellent choice for businesses seeking to enhance their network infrastructure with reliable and secure connectivity solutions.
