●
Cisco standard and extended IP security router ACLs define security policies on routed
interfaces for control-plane and data-plane traffic. IPv6 ACLs can be applied to filter
IPv6 traffic.
●
Port-based ACLs for Layer 2 interfaces allow security policies to be applied on individual
switch ports.
●
Secure Shell (SSH) Protocol, Kerberos, and Simple Network Management Protocol Version
3 (SNMPv3) provide network security by encrypting administrator traffic during Telnet and
SNMP sessions. SSH Protocol, Kerberos, and the cryptographic version of SNMPv3 require
a special cryptographic software image because of U.S. export restrictions.
●
Bidirectional data support on the Switched Port Analyzer (SPAN) port allows Cisco Intrusion
Detection System (IDS) to take action when an intruder is detected.
●
TACACS+ and RADIUS authentication facilitates centralized control of the switch and
restricts unauthorized users from altering the configuration.
●
MAC Address Notification allows administrators to be notified of users added to or removed
from the network.
●
Port Security secures the access to an access or trunk port based on MAC address.
●
Multilevel security on console access prevents unauthorized users from altering the switch
configuration.
●
Bridge protocol data unit (BPDU) Guard shuts down Spanning Tree PortFast-enabled
interfaces when BPDUs are received to avoid accidental topology loops.
●
Spanning Tree Root Guard (STRG) prevents edge devices not in the network
administrator’s control from becoming Spanning Tree Protocol root nodes.
●
IGMP filtering provides multicast authentication by filtering out nonsubscribers and limits
the number of concurrent multicast streams available per port.
●
Dynamic VLAN assignment is supported through implementation of VLAN Membership
Policy Server client capability to provide flexibility in assigning ports to VLANs. Dynamic
VLAN facilitates the fast assignment of IP addresses.
Intelligent Power over Ethernet (PoE) Management
The Cisco Catalyst 3750-E PoE models support Cisco IP phones and Cisco Aironet WLAN access
points, as well as any IEEE 802.3af-compliant end device. The Cisco Catalyst 3750-E-48PD can
support 48 simultaneous full-powered PoE ports at 15.4W with the 1150W power supply.
●
Cisco Discovery Protocol version 2 (CDPv2) allows the Cisco Catalyst 3750-E Series
Switch to negotiate a more granular power setting when connecting to a Cisco powered
device such as IP phones or access points than what is provided by IEEE classification.
●
Per Port power consumption command allows customers to specify maximum power setting
on an individual port.
●
Per Port PoE Power Sensing measures actual power being drawn, enabling more intelligent
control of powered devices.
●
The PoE MIB provides proactive visibility into power usage and allows customers to set
different power level thresholds
