Licensing

Metro Advanced License includes the functions of MPLS, LDP, MPLS-L2VPN, MPLS-L3VPN, VxLAN-BGP-EVPN, and IPFIX. The license is specific to the switch for which it is issued and is not valid on any other switch, so the license is not portable across devices.

Metro Advanced License is offered as a perpetual license, it is applicable to multiple devices, including S5800- 48T4S, S5800-48F4SR, S5850-24T16S, S5850-24T16B, S5850-24XMG, S5850-32S2Q, S5850-48S6Q, S5850- 48S6Q-R, S5850-48S2Q4C, S5850-48T4Q , S8050-20Q4C S5800-48T4S-DC, S5800-48F4SR-DC, S5850-24B4C, S5850-16T16BS2Q.
