Systems and methods for network topology validation
View Patent ↗An information handling system may include a processor and a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution by the processor, cause the processor to determine a topology of connectivity of various components of a system comprising multiple information handling system chassis and apply validation rules to the topology to validate the topology.
1. An information handling system comprising:
a processor; and
a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution by the processor, cause the processor to:
determine a topology of physical network cabling providing connectivity of various components of a system comprising multiple information handling system chassis; and
apply validation rules to the topology to validate the topology, wherein the validation rules include at least one rule based on characteristics of one or more switches integral to the system, wherein the characteristics include respective switch types for the switches and are determined based on a correlation between information received via multicast dynamic name service (mDNS) advertisements and information received via link-layer discovery protocol (LLDP) payloads, and wherein the at least one rule ensures that a plurality of switches integral to a chassis of the system are of the same switch type.
2. The information handling system of claim 1 , the instructions for further causing the processor to generate an indication to a graphical display indicative of violations of the validation rules.
3. The information handling system of claim 1 , wherein the at least one rule ensures that for a first switch of a first chassis of the system coupled to a second switch of a second chassis of the system, that the first switch and second switch are disposed in a particular respective slot of each of the first chassis and the second chassis.
4. The information handling system of claim 1 , wherein the validation rules comprise at least one rule based on characteristics of at least one information handling system chassis of the system.
5. The information handling system of claim 4 , wherein the at least one rule ensures that for a first component of the system coupled to a second component of the system that a chassis group membership of the first component matches that of the second component.
6. The information handling system of claim 1 , wherein the validation rules comprise at least one rule based on characteristics other than a match of a source port of a first component to a destination port of another component.
7. A method comprising:
a processing circuit determining a topology of physical network cabling providing connectivity of various components of a system comprising multiple information handling system chassis; and
the processing circuit applying validation rules to the topology to validate the topology, wherein the validation rules include at least one rule based on characteristics of one or more switches integral to the system, wherein the characteristics include respective switch types for the switches and are determined based on a correlation between information received via multicast dynamic name service (mDNS) advertisements and information received via link-layer discovery protocol (LLDP) payloads, and wherein the at least one rule ensures that a plurality of switches integral to a chassis of the system are of the same switch type.
8. The method of claim 7 , further comprising generating an indication to a graphical display indicative of violations of the validation rules.
9. The method of claim 7 , wherein the at least one rule ensures that for a first switch of a first chassis of the system coupled to a second switch of a second chassis of the system, that the first switch and second switch are disposed in a particular respective slot of each of the first chassis and the second chassis.
10. The method of claim 7 , wherein the validation rules comprise at least one rule based on characteristics of at least one information handling system chassis of the system.
11. The method of claim 10 , wherein the at least one rule ensures that for a first component of the system coupled to a second component of the system that a chassis group membership of the first component matches that of the second component.
12. The method of claim 7 , wherein the validation rules comprise at least one rule based on characteristics other than a match of a source port of a first component to a destination port of another component.
13. An article of manufacture comprising:
a non-transitory computer readable medium; and
computer-executable instructions carried on the computer readable medium, the instructions readable by a processor, the instructions, when read and executed, for causing the processor to:
determine a topology of physical network cabling providing connectivity of various components of a system comprising multiple information handling system chassis; and
apply validation rules to the topology to validate the topology, wherein the validation rules include at least one rule based on characteristics of one or more switches integral to the system, wherein the characteristics include respective switch types for the switches and are determined based on a correlation between information received via multicast dynamic name service (mDNS) advertisements and information received via link-layer discovery protocol (LLDP) payloads, and wherein the at least one rule ensures that a plurality of switches integral to a chassis of the system are of the same switch type.
14. The article of manufacture of claim 13 , the instructions for further causing the processor to generate an indication to a graphical display indicative of violations of the validation rules.
15. The article of manufacture of claim 13 , wherein the validation rules comprise at least one rule based on characteristics of at least one information handling system chassis of the system.
