Protocol-Independent Multicast (PIM) for IP multicast routing within a network that enables the network to receive the multicast

feed requested and for switches not participating in the multicast to be pruned—support for PIM sparse mode (PIM-SM), PIM

dense mode (PIM-DM), and PIM sparse-dense mode



Distance Vector Multicast Routing Protocol (DVMRP) tunneling for interconnecting two multicast-enabled networks across non-

multicast networks

 Is the IP Service license required to allow Layer 3 and Layer 4 lookups for QoS and security?

 No. Both the IP Base and the IP Services licenses allow for Layer 3 and Layer 4 lookups for QoS and security.

 Can the Cisco Catalyst 3560 Series support Cisco GigaStack

or Cisco StackWise technology?

 The Cisco Catalyst 3560 Series does not support Cisco GigaStack technology (available on the Cisco Catalyst 3550, 2950G, and 3500

XLs) or Cisco StackWise technology (available on the Catalyst 3750 Series). However, a cluster of any combination of these

platforms can be managed over a single IP address using the Cisco Network Assistant software. There are more details on Cisco

Network Assistant later in this document.

 Does the Cisco Catalyst 3560 Series support Inter-Switch Link (ISL) VLAN trunking?

 Yes, the Cisco Catalyst 3560 Series supports both 802.1Q trunking and ISL trunking. VLAN trunks can be created from any port

using either standards-based 802.1Q tagging or the Cisco ISL VLAN architecture.

 What are Small Form-Factor Pluggables (SFPs)?

 SFPs are transceivers that provide Gigabit Ethernet connectivity from the Cisco Catalyst 3560 Series to distribution layer switches.

They are functionally equivalent to Gigabit Interface Converters (GBICs), but are much smaller.

 What SFPs are supported on the Cisco Catalyst 3560 Series?

 Cisco Catalyst 3560 Series Switches support 1000BASE-SX, 1000BASE-LX/LH, 1000BASE-ZX, 1000BASE-T, 1000BASE-BX,

1000BASE-CWDM, and 100BASE-FX (supported after 12.2(20)SE) SFP transceivers. In addition, they support the Cisco Catalyst

3560 SFP Interconnect Cable for establishing a low-cost Gigabit Ethernet point-to-point connection.

 What is the Cisco Catalyst 3560 SFP Interconnect Cable?

 The Cisco Catalyst 3560 SFP Interconnect Cable provides for a low-cost point-to-point Gigabit Ethernet connection between Catalyst

3560 switches. The 50-cm cable is an alternative to using SFP transceivers when interconnecting Catalyst 3560 switches through their

SFP ports over a short distance.

 Is there a limit to the number of SFPs that can be used on a Cisco Catalyst 3560 Series Switch?

 No. Users can populate all the SFP ports of any Catalyst 3560 Series Switch with the same SFP or with a combination of

different SFPs.

 Does the Cisco Catalyst 3560 Series have Redundant Power Supply (RPS) support?

 Yes. Maximum power availability for a converged voice and data network is attainable when a Cisco Catalyst 3560 Series Switch is

combined with the Cisco Redundant Power System 675 (RPS 675) for protection against internal power supply failures and an

uninterruptible power supply (UPS) system to safeguard against power outages. For more information on the Cisco RPS 675, go to:

INTELLIGENT SWITCHING

 Why do I need intelligence at the edge of my network?

 Networks are evolving to address four new developments at the network edge:



Increase in desktop computing power

Introduction of bandwidth-intensive applications
