RIP routing protocol (RIPv1 and RIPv2)
RIP is a routing protocol that dynamically adapts to changes of network connections by communicating network topology with other network devices running RIP. You can better control network traffic and improve security by using RIP to route between IP subnets or VLANs.
Selectable queue configuration
By making the number of queues in the switch configurable, this feature optimizes the number of memory buffers according to your applications. The switch supports 2–queue, 4–queue or 8–queue configuration. If you have high–bandwidth requirements and do not use QoS, you can use the 2–queue configuration to improve performance. Similarly, if you temporarily oversubscribe links or use 2900 in a server farm and do not use QoS, you can use the 2–queue configuration to minimize packet loss
Command Authorization
Command Authorization allows less–experienced network administrators to manage the 2900 switches without getting access to all CLI commands. A list of commands can be defined for each network administrator and stored in a RADIUS server. After login, this set of commands is downloaded to the switch, which enforces access only to the authorized commands. This feature also supports a trail of usages for future audit.
BPDU Port Protection prevents DoS attacks using Bridge Protocol Data Unit (BPDU) and improves uptime in networks using Spanning Tree Protocol (STP).
Loop Protection prevents network loops with unmanaged switches.
Uni–directional Link Detection (UDLD) detects problems with network cables and prevents network downtime from fiber breaks.
sFlow enhancement increases (to three) the number of collectors supported and adds CLI commands to set sFlow.
Clear log clears previous events to make the event log easier to read.
Reload commands allow the switch to reboot at a certain time and make is easier to manage remote switches.
DHCP option 82 inserts the switch's IP and port number into client–originated DHCP packets to increase security and improve manageability.
