In general, embodiments relate to a network device, including network device hardware including a processor; and memory comprising instructions which, when executed by the processor, performs a method for creating segment mapping in a network. The method includes entering a fallback mode in response to detecting a fallback scenario, determining, based on the fallback mode, a segment identification (ID) for a client device of the network, wherein the segment ID identifies a segment of the network including a client device, obtaining an Internet Protocol (IP) address to segment ID mapping, wherein the client device is associated with the IP address, and processing at least one packet from the client device using the IP address to segment ID mapping.

Fallback segmentation security

In general, the disclosure relates to a method for creating segment mapping in a network, by a network device. The method includes receiving a segment identification (ID) for a client device of the network from an authentication system. The segment ID identifies a segment of the network including the client device and the network device wherein the segment ID is associated with a media access control (MAC) address of the client device. The network device or a network management system (NMS) determines an internet protocol (IP) address of the client device and the network device creates an IP address to segment ID mapping for the client device using the IP address. The IP address to segment ID mapping is provided to the NMS for distribution to remaining network devices of the network. At least one packet of the client device is processed using the IP address to segment ID mapping.

System for assigning and distributing device security segment identification

A network device includes storage. The network device also includes a forwarding information manager. The storage stores forwarding information. The storage also stores information source rankings. The forwarding information manager obtains information from a source. The information source rankings include a ranking associated with the source. The forwarding information manager makes a determination, based on the information source rankings, that the source is undesirable. The forwarding information manager discards the information without processing the information based on the determination.

System and method for managing computing resources

Systems and methods are provided herein for an improved method of Zero-Touch Provisioning (ZTP) where a first switch receives a virtual local area network (VLAN) identifier from a second switch, allowing the first switch to reach a dynamic host configuration protocol (DHCP) server. This may be accomplished by a first switch receiving a VLAN identifier from a second switch. The first switch then transmits a DHCP discover message using the VLAN identifier. The first switch then receives reachability information for a ZTP server from the DHCP server. The first switch uses the reachability information to establish a provisioning session between the first switch and the ZTP server.

Method and system for reducing multicast traffic loss including configuring, on a primary DR including a first configured DR priority, a DR parameter including a value and an attribute; sending to a secondary DR, after a PIM interface comes up, a PIM hello message including a default DR priority lower than a second configured priority of the secondary DR; sending to the secondary DR, after the primary DR reaches a system-up state, a PIM hello message including the default DR priority; performing DR functionality, by the primary DR, after reaching the system-up state; and sending to the secondary DR, after waiting a time period corresponding to the value of the DR parameter, a PIM hello message including the first configured DR priority, where the primary DR waits to send the last PIM hello message to the secondary DR after the time period based on the attribute of the DR parameter.
