Cisco IE2100 Series CNS embedded agents for automating switch management, configuration
storage, and delivery
Dynamic Host Configuration Protocol (DHCP) for automating configuration of switch information
(such as IP address, default gateway, host name, and Domain Name System [DNS] and TFTP server
names)
Directed unicast requests to a DNS server for identifying a switch through its IP address and its
corresponding host name and to a TFTP server for administering software upgrades from a TFTP
server
Address Resolution Protocol (ARP) for identifying a switch through its IP address and its
corresponding MAC address
Cisco Discovery Protocol (CDP) versions 1 and 2 for network topology discovery and mapping
between the switch and other Cisco devices on the network
Network Time Protocol (NTP) for providing a consistent timestamp to all switches from an external
source
Cisco IOS File System (IFS) for providing a single interface to all file systems that the switch uses
In-band management access for up to 16 simultaneous Telnet connections for multiple CLI-based
sessions over the network
In-band management access for up to five simultaneous, encrypted SSH connections for multiple
CLI-based sessions over the network (requires the cryptographic version of the switch software
image)
In-band management access through SNMP versions 1 and 2c, and 3 get and set requests
Out-of-band management access through the switch console port to a directly attached terminal or
to a remote terminal through a serial connection or a modem
HSRP for command switch and Layer 3 router redundancy
UniDirectional Link Detection (UDLD) and aggressive UDLD for detecting and disabling
unidirectional links on fiber-optic interfaces caused by incorrect fiber-optic wiring or port faults
IEEE 802.1D Spanning Tree Protocol (STP) for redundant backbone connections and loop-free
networks. STP has these features:
–
Up to 128 spanning-tree instances supported
–
Per-VLAN spanning-tree plus (PVST+) for balancing load across VLANs
Rapid PVST+ for balancing load across VLANs and providing rapid convergence of
–
spanning-tree instances
UplinkFast and BackboneFast for fast convergence after a spanning-tree topology change and
–
for achieving load balancing between redundant uplinks, including Gigabit uplinks
IEEE 802.1s Multiple Spanning Tree Protocol (MSTP) for grouping VLANs into a spanning-tree
instance and for providing multiple forwarding paths for data traffic and load balancing and
IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) for rapid convergence of the spanning tree by
immediately transitioning root and designated ports to the forwarding state
