Table A-1 Field Attributes for Multicast Rout Display

Field

Description

 

 

Origin-Subnet

The source address and the number of bits in the subnetwork

From-Gateway

The interface address of the gateway

Metric

The hop count

Tmr

The amount of time, in seconds, since the routing table entry was

 

last reset

In-If1

Interface number on which that gateway is connected. This is the

 

interface where traffic is expected to originate.

 

T represents the tunnel; P denotes that a prune has been sent to

 

this tunnel.

Out-If1

Set of interfaces that the traffic will be flooded out on. I repre-

 

sents the interface.

 

 

1In-If and Out-If

Together, these attributes define a Spanning Tree configuration. Interfaces

 

that comprise loops will be disabled

The multicast cache contains the IP source address and destination address for packets observed on the system. The multicast cache shows you how information is routed over interfaces and ports in your system.

To display all learned routes in the multicast cache:

1From the top level of the Administration Console, enter:

ip multicast cacheDisplay

You are prompted for the multicast source address.

2Enter the multicast source subnetwork address. You are prompted for the multicast group address.

3Enter the multicast group address.

The DVMRP status and IGMP status appear on the screen.

6000 specifications

The 3Com 6000 series, launched in the late 1990s, was a significant advancement in networking technology, designed to meet the growing demands of enterprise-level networking. This series provided powerful solutions for businesses seeking reliable, efficient, and scalable networking capabilities.

At its core, the 3Com 6000 series featured a modular design, allowing companies to customize their networks according to specific needs. This flexibility meant that organizations could add or replace components as their networking requirements evolved, ensuring investment protection and a tailored approach to connectivity. The ability to scale was particularly important for businesses that anticipated growth or change in operational demands.

One of the standout features of the 3Com 6000 was its advanced switching capabilities. The series employed high-performance switching technologies that supported various protocols, including Fast Ethernet and Gigabit Ethernet. This versatility made it suitable for diverse environments, from small offices to large corporate settings. The 3Com 6000 switches were engineered to deliver high throughput and low latency, crucial for applications requiring real-time data transfer.

The series also supported a range of network management tools, enhancing operational efficiency. With SNMP (Simple Network Management Protocol) support, network administrators could easily monitor and manage network performance, troubleshoot issues, and configure devices from a centralized location. This capability significantly streamlined network operations, reducing downtime and optimizing resource allocation.

Security was another significant concern addressed by the 3Com 6000. The series incorporated robust security features, including access control lists (ACLs) and VLAN (Virtual Local Area Network) support. These features allowed network administrators to segment traffic and enforce security policies, protecting sensitive data and ensuring compliance with organizational standards.

Moreover, the 3Com 6000 series was designed with energy efficiency in mind, reflecting a growing awareness of the environmental impact of IT infrastructure. By implementing power-saving features, the series helped organizations reduce their overall energy consumption while maintaining optimal network performance.

In summary, the 3Com 6000 series stood out for its modularity, advanced switching capabilities, extensive management tools, strong security features, and energy efficiency. It represented a forward-thinking solution for enterprises aiming to build robust network infrastructures capable of supporting a wide range of applications and services. As organizations increasingly relied on networked systems, the 3Com 6000 played a crucial role in shaping the landscape of enterprise networking.
