Simplified configuration and connectivity:
◦
Dynamic Trunking Protocol (DTP) facilitates dynamic trunk configuration across all switch ports.
◦
Port Aggregation Protocol (PAgP) automates the creation of Cisco Fast EtherChannel groups or Gigabit
EtherChannel groups to link to another switch, router, or server.
◦
Link Aggregation Control Protocol (LACP) allows the creation of Ethernet channeling with devices that
conform to IEEE 802.3ad. This feature is similar to Cisco EtherChannel technology and PAgP.
◦
Unidirectional Link Detection Protocol (UDLD) and aggressive UDLD allow unidirectional links caused by
incorrect fiber-optic wiring or port faults to be detected and disabled on fiber-optic interfaces.
◦
Cisco VLAN Trunking Protocol (VTP) Version 3 supports dynamic VLANs and dynamic trunk
configuration across all switches.
●
Efficient switch operation:
◦
Switching database manager (SDM) templates, VLAN template (specific to LAN Base license level), and
advanced template allow the administrator to automatically optimize the ternary content-addressable
memory (TCAM) allocation to the desired features based on deployment-specific requirements.
◦
Local proxy Address Resolution Protocol (ARP) works in conjunction with private VLAN edge to
minimize broadcasts and maximize available bandwidth.
◦
Stacking master configuration management with Cisco StackWise-480 technology helps make sure that
all switches are automatically upgraded when the master switch receives a new software version.
Automatic software version checking and updating help ensure that all stack members have the same
software version.
◦
Trivial File Transfer Protocol (TFTP) reduces the cost of administering software upgrades by
downloading from a centralized location.
◦
Network Timing Protocol (NTP) provides an accurate and consistent timestamp to all intranet switches.
●
Multicast:
◦
Optimized multicast for wired plus wireless: Cisco Catalyst 3850 offers greater multicast efficiency by
receiving only one multicast stream and replicating it for all connected wired plus wireless devices
connected to that switch.
◦
Internet Group Management Protocol (IGMP) v1, v2, v3 snooping for IPv4: multicast listener discovery
(MLD) v1 and v2 snooping provides fast client joins and leaves of multicast streams and limits
bandwidth-intensive video traffic to only the requestors.
●
Monitoring:
◦
Remote Switch Port Analyzer (RSPAN) allows administrators to remotely monitor ports in a Layer 2
switch network from any other switch in the same network.
◦
For enhanced traffic management, monitoring, and analysis, the Embedded Remote Monitoring
(RMON) software agent supports four RMON groups (history, statistics, alarms, and events).
◦
Layer 2 traceroute eases troubleshooting by identifying the physical path that a packet takes from
source to destination.
◦
Wireless RF management provides both real-time and historical information about RF interference
affecting network performance across controllers using systemwide Cisco CleanAir technology
integration.
