Model Brand CISCO Series Catalyst 2955 Model WS-C2955T-12 Spec Standards IEEE 802.1x support IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) IEEE 802.1s Multiple Spanning Tree Protocol (MSTP) IEEE 802.3x full duplex on 10BASE-T, 100BASE-TX, and 1000BASE-T ports IEEE 802.1D Spanning-Tree Protocol IEEE 802.1p CoS prioritization IEEE 802.1Q VLAN IEEE 802.3 10BASE-T specification IEEE 802.3u 100BASE-TX specification IEEE 802.3ab 1000BASE-T specification IEEE 802.3ad Link Aggregation Control Protocol (LACP) IEEE 802.3ah Ethernet in the First Mile (EFM) RMON I and II standards SNMPv1, SNMPv2c, and SNMPv3 Ports 12 x 10/100 ports 2 x 10/100/1000BASE-T ports Speed 10/100Mbps + 1000Mbps MAC Address Table 8000 Buffer Memory 8 MB memory architecture shared by all ports Up to 32 MB SDRAM and 16 MB Flash memory Security Filtering of incoming traffic flows based on Layer 2, Layer 3, or Layer 4 ACPs prevents unauthorized data flows Private 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.
