Overview

The analyzer or RMON probe will see the data as if it were directly connected to the LAN segment of the source port.

The VLAN redirect function is similar to the port redirect function except that the frames received by the device are redirected to a designated destination port according to the VLAN classification of the frames received. The VLAN redirect function does not support redirecting errors, and is only supported when the device is operating as an 802.1Q switch. Multiple VLANs can be directed to the same ports.

1.1.8Rate Limiting

The Rate Limiting feature enables the SmartSwitch device to have control of traffic rates on a per-port, per-priority basis. The network administrator can configure a rate limit (from 100 kbps to 1 Gbps) for a given port with an associated list of IEEE 802.1p priorities (which can include one, some, or all of the eight priority levels defined in 802.1p). Each rate limit is specified as an inbound or an outbound limit. The combined rate of all traffic on the port that matches the listed priorities cannot exceed the programmed limit. If the rate exceeds the defined limit, frames are dropped until the rate falls below the limit.

Administrators can configure up to four rate limit rules per port; however, each rule must not include conflicting 802.1p priority values. In order to control traffic inbound and outbound on the same port, two rate limit rules must be configured (one inbound and one outbound). Since the rate limiting operation occurs after the processing of the multi-layer classification rules, the two features can be combined to provide application-aware rate limiting.

NOTE

This traffic rate function is not supported on ports configured as SmartTrunk ports.

For more information about the application of the Rate Limiting function, refer to the Local Management User’s Guide .

1.1.9GARP Switch Operation

Some or all ports on the switch may be activated to operate under the Generic Attribute Registration Protocol (GARP) applications, GARP VLAN Registration Protocol (GVRP) and/or GARP Multicast Registration Protocol (GMRP).

GARP is a protocol, or set of rules, that outlines a mechanism for propagating the port state and/or user information throughout a bridged LAN to keep track of users and VLANs on the network fabric. MAC bridges and end users alike can take part in the registration and de-registration of GARP attributes such as VLAN and multicast group membership. For more details on how GVRP

Its architecture supports both 10BASE-T and 100BASE-TX Ethernet standards, providing flexibility in deploying a variety of network configurations. The switch also employs innovative packet-switching technology, ensuring low-latency communication and enhanced throughput, which is critical for bandwidth-intensive applications.

On the other hand, the 6H259-17 acts as a versatile router and works seamlessly with the 6H258-17 switch, creating a cohesive networking solution. This model is equipped with a robust routing protocol suite, including RIP and OSPF, to facilitate intelligent data routing across networks. Its ability to accommodate various WAN interfaces further enhances its adaptability in different networking environments, making it suitable for both small businesses and larger enterprise setups.

One of the key characteristics of both models is their modular design, which allows for easy upgrades and expansions as the networking requirements grow. Users can invest in additional modules or line cards, enabling them to scale their systems without the need for complete replacements. This feature not only extends the lifespan of the equipment but also aligns with cost-effective budgeting strategies.

In terms of security, Cabletron Systems has integrated sophisticated features into both products to safeguard data integrity and prevent unauthorized access. The ability to implement VLANs and access control lists ensures that only authorized users can access sensitive information. This focus on security is paramount in today’s landscape, where data breaches pose significant risks to organizations of all sizes.

Additionally, both the 6H258-17 and 6H259-17 are designed for easy management and monitoring. With a user-friendly interface and support for SNMP, network administrators can efficiently oversee network activities, troubleshoot issues, and optimize performance.

In conclusion, the Cabletron Systems 6H258-17 and 6H259-17 represent powerful networking solutions that combine performance, scalability, security, and ease of management. Their advanced technologies make them a valuable choice for organizations looking to enhance their network infrastructure while ensuring future growth and adaptability.
