Which statement describes the function of the SPAN tool used in a Cisco switch?
- It supports the SNMP trap operation on a switch.
- It provides interconnection between VLANs over multiple switches.
- It is a secure channel for a switch to send logging to a syslog server.
- It copies the traffic from one switch port and sends it to another switch port that is connected to a monitoring device.
| Answers Explanation & Hints:
To analyze network traffic passing through a switch, switched port analyzer (SPAN) can be used. SPAN can send a copy of traffic from one port to another port on the same switch where a network analyzer or monitoring device is connected. SPAN is not required for syslog or SNMP. SPAN is used to mirror traffic, while syslog and SNMP are configured to send data directly to the appropriate server. |
