Chapter 7: Command-Line Management

2. Usage:

Use this command to enable the BPDU (Bridge Protocol Data Unit) Guard feature on a bridge.

Use the no parameter with this command to disable the BPDU Guard feature on a bridge.

When the BPDU Guard feature is set for a bridge, all portfast-enabled ports of the bridge that have bpdu-guard set to default shut down the port on receiving a BPDU. In this case, the BPDU is not processed.

3. Command Syntax:

bridge GROUP spanning-tree portfast bpdu-guard no bridge GROUP spanning-tree portfast bpdu-guard GROUP <1-1> Bridge-group ID used for bridging.

4. Example:

The following example enables the BPDU Guard feature on bridge GROUP (1): switch_a(config)#bridge 1 spanning-tree portfast bpdu-guard switch_a(config)#

Error disable timeout configuration:

1. Command Mode: Configure mode

Logon to Configure Mode (Configure Terminal Mode). The switch_a(config)# prompt will show on the screen. switch_a(config)#

2. Usage:

Use this command to enable the timeout mechanism for the port to be enabled back for a bridge.

Use the no parameter with this command to disable the timeout mechanism for the port to be enabled back for a bridge.

3. Command Syntax:

bridge GROUP spanning-tree errdisable-timeout enable no bridge GROUP spanning-tree errdisable-timeout enable GROUP <1-1> Bridge-group ID used for bridging.

4. Example:

The following example enables the timeout mechanism for the port to be enabled back for bridge GROUP (1): switch_a(config)#bridge 1 spanning-tree errdisable-timeout enable

switch_a(config)# Interval:

1. Command Mode: Configure mode

Logon to Configure Mode (Configure Terminal Mode). The switch_a(config)# prompt will show on the screen. switch_a(config)#

Black Box has established itself as a leader in providing robust networking solutions, and its range of hardened managed Ethernet switches, including the LEH1104A-4MMST, LEH1008A-2MMST, LEH906A-2SFP, and LEH906A-2MMSC, exemplifies this commitment. These switches are specifically designed to withstand the harsh environments often found in industrial and outdoor settings, making them ideal for applications such as transportation, utility management, and manufacturing.

The LEH1104A-4MMST model features four 10/100/1000 Mbps Ethernet ports, providing a flexible solution for networks requiring fast and reliable connectivity. It supports Power over Ethernet (PoE), enabling both data and power to be transmitted via a single cable, thereby simplifying installations and reducing wiring costs. This model also includes advanced features such as VLAN support, IGMP Snooping, and Quality of Service (QoS), ensuring optimized traffic management and network efficiency.

Similarly, the LEH1008A-2MMST switch offers eight ports and is built to handle a higher volume of connections without sacrificing performance. It boasts Layer 2 and Layer 3 management capabilities, allowing for complex network configurations and enhanced security measures such as port security and access control lists. The robust design and metal enclosure protect it from dust, moisture, and extreme temperatures.

The LEH906A-2SFP and LEH906A-2MMSC switches focus on modularity and connectivity flexibility, with SFP (Small Form-factor Pluggable) ports that enable users to choose the appropriate transceivers for their specific distances and media types, whether they require fiber or copper connections. Both models support dual-power inputs for redundancy and reliability, critical features for mission-critical applications.

All these switches are crafted to comply with industrial standards, ensuring reliable performance in diverse applications. Features such as redundant power supplies, fast recovery times, and support for protocols like SNMP (Simple Network Management Protocol) make network monitoring and management efficient and hassle-free.

In summary, Black Box’s hardened managed Ethernet switches, including the LEH1104A-4MMST, LEH1008A-2MMST, LEH906A-2SFP, and LEH906A-2MMSC, provide a perfect blend of durability, scalability, and management capabilities. These switches are engineered to meet the rigorous demands of industrial networking while ensuring seamless connectivity for diverse applications, making them an excellent investment for organizations looking to enhance their network infrastructure.
