Port mirroring. Enables traffic on a port to be simultaneously sent to a network analyzer for monitoring. Dual flash images. Provides independent primary and secondary operating system files for backup while upgrading. Limited Command Line Interface (CLI). Facilitates in the deployment and initial configuration of the unit. Supports troubleshooting actions as well. Intuitive Web browser-based management. Allows for easy customization of the switch even by non-technical users. IEEE 802.1AB Link Layer Discovery Protocol (LLDP). Advertises and receives management information from adjacent devices on a network, facilitating easy mapping by network management applications. SNMPv1, v2c, and v3. Facilitates remote management of the switch, as the device can be discovered and monitored from an SNMP management station. Four-high true stacking simplifies administration of multiple devices. Create a single logical managed unit with up to four HPE OfficeConnect 1950 switches. Balance connections across multiple units with Link Aggregation (LACP) for enhanced network resiliency. Stack using affordable Cat 6a, or long distance fiber, or localized DAC cables. Complete session logging. Provides detailed information for problem identification and resolution. Network Time Protocol (NTP). Synchronizes timekeeping among distributed time servers and clients, keeps timekeeping consistent among all clockdependent devices within the network so that the devices can provide diverse applications based on the consistent time. Secure Web-management sessions with HTTPS / SSL. Encrypts and otherwise protects management sessions through HTTP Secure (HTTPS). Prevents snooping of sensitive management information such as passwords.
