Cisco Catalyst 2955T 12 Switch
The Cisco Catalyst 2955T-12 is a member of the Catalyst 2955 Series, and is an industrial-grade switch that provides Fast Ethernet and Gigabit Ethernet connectivity for deployment in harsh environments. With a range of copper and fiber uplink options, the Catalyst 2955 operates in environments such as industrial networking solutions (industrial Ethernet deployments), intelligent transportation systems (ITS), and transportation network solutions. It is also suitable for many military and utility market applications where the environmental conditions exceed the specifications of other commercial switching products.
Embedded in Cisco Catalyst 2955 Series switches is Cisco Cluster Management Suite (CMS) Software. This network management solution allows administrators to easily configure features, monitor performance, and troubleshoot multiple Cisco Catalyst switches using a standard Web browser. For larger deployments, Cisco Catalyst 2955 Series switches support Simple Network Management Protocol (SNMP)-based network management platforms such as CiscoWorks.
Features
- Rugged: Implements industrial-grade components, a compact form factor, convection cooling, and relay output signaling. Designed to operate at extreme temperatures and under extreme vibration and shock.
- Intelligent: Offers Cisco IOSŪ Software functionality for traditional data, video and voice services with enhanced intelligent services features for additional security, advanced QoS, high availability, and manageability.
- Twelve 10/100 ports and two 10/100/1000BASE-TX (Copper) uplinks
- Enhanced Image (EI) Software

| Security | Filtering of incoming traffic flows based on Layer 2, Layer 3, or Layer 4 ACPs prevents unauthorized data flowsPrivate VLAN edge provides security and isolation between ports on a switch, ensuring that voice traffic travels directly from its entry point to the aggregation device through a virtual path and cannot be directed to a different port. Support for the 802.1x standard allows users to be authenticated, regardless of which LAN port they are accessing, and provides unique benefits to customers who have a large base of mobile (wireless) users accessing the network. 802.1x with VLAN assignment allows a dynamic VLAN assignment for a specific user, regardless of where the user is connected. 802.1x with voice VLAN gives an IP phone access to the voice VLAN, regardless of the authorized or unauthorized state of the port. 802.1x with port security authenticates the port and manages network access for all MAC addresses, including the clients\'. SSH and SNMPv3 provide network security by encrypting administrator traffic during Telnet and SNMP sessions. Port security secures the access to a port based on the MAC address of a user\'s device. The aging feature removes the MAC address from the switch after a specific timeframe to allow another device to connect to the same port. MAC address notification allows administrators to be notified of new users added or removed from the network. Spanning-tree root guard (STRG) prevents edge devices not in the network administrator\'s control from becoming Spanning-Tree Protocol root nodes. The Spanning-Tree Protocol PortFast/bridge protocol data unit (BPDU) guard feature disables access ports with Spanning-Tree Protocol PortFast enabled upon reception of a BPDU, and increases network reliability, manageability, and security. Multilevel console access security prevents unauthorized users from altering the switch configuration. |
