Simplified Paramiko Library to Fetch Data From MultiVendor Network Devices
- Cisco IOS
- Cisco IOS-XE
- Cisco NX-OS
- Cisco IOS-XR
- Juniper Junos
- Huawei VRP5/8
- ZTE ZXROS
- DELL OS10
- Ericsson IPOS
- Nokia SROS
Script is based on paramiko and catches device-prompt to understand the output is fetched, thus there is a strong possibility that script could work with many network devices from different vendors, i only do not have the chance to test.
- huawei-vrp
- cisco-ios
- cisco-iosxe
- cisco-iosxr
- cisco-nxos
- junos
- dell-os10
- zte-zxros
- ericsson-ipos
- nokia-sros
For the above device type pagination commands (e.g. "terminal length 0") send automatically.
