U ka sebelisa Cisco CSR 1000v VM u sebelisa data e tloaelehileng feela ho Cisco IOS XE Gibraltar 16.12.1 kapa litokollo tse latelang.
- Ho hlophisa data e tloaelehileng,
- Ho fihlella Custom Data,
- Ho netefatsa Customer Data Configuration,
Ho fetola Custom Data
Ho hlophisa data e ikhethileng, lokisa lintlha tse latelang:
- Sebopeho sa IOS
- Mengolo
- Bopaki ba sengoloa
- Sephutheloana sa Python
- Ho fana ka laesense
U ka beha thepa ka a file ka tatellano efe kapa efe. Litlhaloso tse latelang tsa thepa li hlakisa ho its'etleha lipakeng tsa thepa, haeba e teng. Bona example bootstrap files ho: https://github.com/csr1000v/customdata-examples.
Ka mor'a ho hlalosa thepa ea data e tloaelehileng, u ka khona ho fumana script ea ho qala kapa data e tloaelehileng file ho sebelisa CLI joalo ka ha ho hlalositsoe ho Accessing the Custom Data section.
Ho lokisa thepa ea IOS Configuration
Haeba u batla ho qala tlhophiso ea IOS ka Day0, lokisa thepa ea IOS Configuration. Sheba tse latelang IOS tlhophiso exampLe:
- Karolo: Tlhophiso ea IOS
