Check the switch s access bandwidth
#show interface summary command provides bandwidth utilization of each Cisco switch interface, VLAN and port channels. You can either measure bits per sec using RXBS/TXBS fields or packets per sec using RXPS/TXPS fields. Additionally you also get to know counts of pkts dropped in. Is there a way I can find out the amount of bandwidth i'm using on a particular interface on a 4507 cisco multi-layer switch? It is a gig port and I have it setup for monitoring (spanning) and I see packets being dropped in the "Total Output Drops" area. Monitoring must include both the switches themselves and their ports, tracking status, bandwidth, packet flow, and errors to detect malfunctions or misconfigurations. Combining SNMP, flow protocols, and modern interfaces provides a complete view of network traffic and device health without. Bandwidth Monitoring helps you track usage across any physical (Ethernet, Fast Ethernet, or Gigabit Ethernet) or virtual network interface on SNMP-managed devices such as switches, routers, printers, or servers with SNMP software installed.
