Stack Management

Note that in the above example (figure 9-37)you cannot use the public community through the Commander to access any of the Member switches. For example, you can use the public community to access the MIB in switches 1 and 3 by using their unique IP addresses. However, you must use the red or blue community to access the MIB for switch 2.

snmpget <MIB variable> 10.31.29.100 blue@sw2

Using the CLI To Disable or Re-Enable Stacking

In the default configuration, stacking is enabled on the SMC6624M. You can use the CLI to disable stacking on the switch at any time. Disabling stacking has the following effects:

■Disabling a Commander: Eliminates the stack, returns the stack Mem- bers to Candidates with Auto Join disabled, and changes the Commander to a stand-alone (nonstacking) switch. You must re-enable stacking on the switch before it can become a Candidate, Member, or Commander.

■Disabling a Member: Removes the Member from the stack and changes it to a stand-alone (nonstacking) switch. You must re-enable stacking on the switch before it can become a Candidate, Member, or Commander.

■Disabling a Candidate: Changes the Candidate to a stand-alone (non- stacking) switch.

Syntax: no stack

(Enables stacking on the switch.)

Transmission Interval

All switches in the stack must be set to the same transmission interval to help ensure proper stacking operation. SMC recommends that you leave this parameter set to the default 60 seconds.

Syntax: stack transmission-interval <seconds>

Stacking Operation with Multiple VLANs Configured

Stacking uses the primary VLAN in a switch. In the factory-default configura- tion, the DEFAULT_VLAN is the primary VLAN. However, you can designate any VLAN configured in the switch as the primary VLAN. (See “Which VLAN Is Primary?” on page 9-51.)

When using stacking in a multiple-VLAN environment, the following criteria applies:

SMC6624M specifications

SMC Networks SMC6624M is a robust and versatile managed switch designed to meet the needs of enterprises seeking reliable network solutions. This device features 24 Gigabit Ethernet ports that allow for high-speed data transfer, making it ideal for environments that demand high bandwidth. The SMC6624M is particularly suited for small to medium-sized businesses that require a powerful network backbone to support various applications, including voice, video, and data transmission.

One of the standout features of the SMC6624M is its Layer 2 and Layer 3 switching capabilities, enhancing the flexibility and efficiency of network management. The switch supports VLANs (Virtual Local Area Networks), which allow administrators to segment network traffic for improved security and performance. This capability is essential for organizations looking to optimize their network resources and apply policies that enhance security.

The SMC6624M also integrates advanced Quality of Service (QoS) features, enabling the prioritization of network traffic. This is particularly useful for applications such as VoIP and video conferencing, where maintaining low latency and jitter is crucial for ensuring a seamless user experience. Users can define traffic classes and manage bandwidth allocation, which helps in maintaining the quality of critical applications even during peak usage times.

In terms of connectivity and performance, the SMC6624M includes 4 Gigabit SFP ports, allowing for fiber optic connections to extend network reach and provide flexibility in deployment. The ability to take advantage of high-speed fiber connections means businesses can scale their networks as needed without significant infrastructure changes.

Management options for the SMC6624M are comprehensive. It supports SNMP (Simple Network Management Protocol) for monitoring and managing network performance effectively. Additionally, the switch can be configured using a web-based interface, command-line interface (CLI), or through SNMP, providing flexibility to network administrators with different preferences and expertise.

Furthermore, the SMC6624M is built with a fanless design, which ensures quiet operation and is energy efficient. Its compact form factor and sturdy build make it suitable for installation in various environments, including data centers and office settings.

Overall, the SMC Networks SMC6624M stands out for its combination of speed, flexibility, and management features, making it an excellent choice for businesses looking to enhance their network infrastructure. With a focus on reliability and performance, this managed switch promises to deliver the capabilities that today's modern networks demand.
