Q

is this switch/router ipv6 and ipv4 ?

Posted on 06/23/2011 at 06:56AM by Anonymous
A

This is a layer 2 switch and it will be able to forward IPv6 traffic between its ports. There is no need to support a layer 3 protocol to forward frames at layer 2.
However, you will not be able to configure an IPv6 address on this device to manage it, as it doesn’t have any IPv6 support on layer 3.

The Catalyst 2948G-L3 provides an aggregate throughput of more than 10 Mpps for Layer 3 switching. These data rates apply not only to IP and IPX traffic but also to IP multicast and bridged traffic and are a result of using high-speed application-specific integrated circuit (ASIC) technology on each port to perform true Layer 3 switching. The Catalyst 2948G-L3 supports a high-performance architecture with 22 Gbps bandwidth. The switch fabric is capable of supporting all 48 10/100 ports and two Gigabit uplinks simultaneously at wire speed.

The Catalyst 2948G-L3 is housed in a 1.5 rack unit (RU) chassis and can be provisioned with an optional external redundant power supply. It supports a 22 Gbps shared-memory, fully non-blocking switch fabric, high- performance RISC processor that provides the routing intelligence and individual port-based ASICs for the Layer 3 switching. The Catalyst 2948G-L3 uses Cisco Express Forwarding (CEF), which has been developed for the Cisco 12000 series gigabit switch router (GSR), the Catalyst 8500, and the Cisco 7500. This technology provides Layer 3 switching based on a topology map of the entire network that is distributed to each port-based ASIC, allowing it to make autonomous switching decisions without the involvement of a centralized CPU.

    Security Features: The Catalyst 2948G-L3 has the ability to prevent security breaches via the use of both IP and IPX access lists. This is useful in preventing users from accessing certain applications or services. The Catalyst 2948G-L3 supports both inbound and outbound access lists on its two Gigabit Ethernet interfaces. These access lists can be defined similar to any Cisco IOS router as standard IPX access lists as well as standard and extended IP-based access lists. Having both inbound and outbound control of packets on the Gigabit Ethernets allows network managers to prevent traffic both on egress as well as ingress on the 10/100 Ethernet ports. In addition, the Catalyst 2948G-L3 will have the capability to prevent traffic communication between 10/100 Ethernet ports. When enabled, users on the 10/100 ports can only send traffic to the Gigabit Ethernet ports and not to each other.
