Multi-Vendor Network CLI Cheat Sheet: IOS XR, Junos, SR OS, VRP

Network engineers who operate multi-vendor environments spend a surprising amount of time translating commands between Cisco, Juniper, Nokia and Huawei — and mistranslations are a leading cause of change-window incidents. A side-by-side CLI reference eliminates the guesswork: the same task has four different syntaxes, and the differences are systematic rather than arbitrary. This cheat sheet compares configuration models, diagnostic commands, and routing protocol configuration across IOS XR, Junos, SR OS and VRP.

Configuration Models: Commit vs. Apply-and-Save

Juniper Junos and Nokia SR OS use a transactional candidate model; Cisco IOS XR also requires an explicit commit; Huawei VRP applies commands immediately and you save explicitly. Setting a hostname:

# Cisco IOS XR
configure terminal → hostname R1 → commit
# Juniper Junos
configure → set system host-name R1 → commit   (rollback with 'rollback 0')
# Nokia SR OS
configure → system name R1 → commit → save
# Huawei VRP
system-view → sysname R1 → return → save

Mistaking write memory for commit on Junos does nothing — knowing which model each platform uses prevents these silent no-ops.

Diagnostic Command Equivalents

Ping, Traceroute and Capture

# Extended ping with source interface
Cisco:  ping 10.0.0.2 source loopback0
Junos:  ping 10.0.0.2 source 192.168.1.1
Nokia:  ping 10.0.0.2 source-address 192.168.1.1
Huawei: ping -a 192.168.1.1 10.0.0.2
# Traffic capture
Cisco:  monitor capture test interface gig0/0 both match ip any
Junos:  monitor traffic interface ge-0/0/0
Huawei: capture-packet interface gig0/0/0

OSPF and BGP Equivalents

# OSPF on a single interface
Cisco IOS XR: router ospf 1 / area 0 / interface GigabitEthernet0/0/0/0 / passive disable
Junos:  set protocols ospf area 0 interface ge-0/0/0 passive
Nokia:  configure router ospf area 0.0.0.0 interface "to-core"
Huawei: ospf 1 / area 0 / network 10.0.0.0 0.0.0.255
# BGP neighbor
Cisco:  neighbor 10.0.0.1 remote-as 65001
Junos:  set protocols bgp group external peer-as 65001 neighbor 10.0.0.1
Nokia:  configure router bgp neighbor 10.0.0.1 peer-as 65001
Huawei: bgp 65000 / peer 10.0.0.1 as-number 65001
