● Voice VLAN aware port security and BPDU Guard allow Voice VLAN traffic to not be disrupted
Networkwide
Security Features
when security violations occur.
(continued)
● IGMP filtering provides multicast authentication by filtering out no subscribers and limits the number
of concurrent multicast streams available per port.
● Dynamic VLAN assignment is supported through implementation of VLAN Membership Policy
Server (VMPS) client functions to provide flexibility in assigning ports to VLANs. Dynamic VLAN
helps enable the fast assignment of IP addresses.
● Cisco Network Assistant software security wizards ease the deployment of security features for
restricting user access to a server as well as to a portion of or the entire network.
● Up to 512 (ACEs) are supported, with two profiles: Security (384 Security ACL entries and 128 QoS
policies), and QoS (128 Security ACL entries and 384 QoS policies).

Cisco Catalyst 2975 LAN Base Switch Hardware
Description
Specification
Performance
● 32 Gbps switching fabric
● 38.7 Mpps forwarding rate based on 64-byte packets:
● 128 MB DRAM
● 32 MB flash memory
● Configurable up to 8000 MAC addresses
● Configurable up to 255 IGMP groups
● Configurable maximum transmission unit (MTU) of up to 9000 bytes, with a maximum Ethernet
frame size of 9018 bytes (Jumbo frames) for bridging on Gigabit Ethernet ports, and up to 1998
bytes for bridging of Multiprotocol Label Switching (MPLS) tagged frames on 10/100/1000 ports
Connectors
● 10BASE-T ports: RJ-45 connectors, 2-pair Category 3, 4, or 5 unshielded twisted-pair (UTP) cabling
and Cabling
● 100BASE-TX ports: RJ-45 connectors, 2-pair Category 5 UTP cabling
● 1000BASE-T ports: RJ-45 connectors, 4-pair Category 5 UTP cabling
● 1000BASE-T SFP-based ports: RJ-45 connectors, 4-pair Category 5 UTP cabling
● 1000BASE-SX, -LX/LH, -ZX, -BX and CWDM SFP-based ports: LC fiber connectors
(single/multimode fiber)
● 100BASE-FX: LC fiber connectors (single/multimode fiber).
● Customers can provide power to a switch by using either the internal power supply or the Cisco
Power Connectors
RPS 2300 or RPS 675. The connectors are located at the back of the switch.
Internal Power-Supply Connector:
● The internal power supply is an autoranging unit.
● The internal power supply supports input voltages between 100 and 240VAC.
● Use the supplied AC power cord to connect the AC power connector to an AC power outlet.
Cisco RPS Connector:
● The connector offers connection for an optional Cisco RPS 2300 that uses AC input and supplies
DC output to the switch.
● The connector offers a 2300W redundant power system that supports up to six external network
devices and provides power to two failed devices at a time.
● The connector automatically senses when the internal power supply of a connected device fails and
provides power to the failed device, preventing loss of network traffic.
● Only the Cisco RPS 2300 (model PWR-RPS2300) or Cisco RPS 675 should be attached to the
redundant-power-system receptacle.
