Management Services

Management services let labs exercise operational flows: remote login, file copy, simple HTTP interactions, and device-to-device management reachability.

Support level

Area	Level	Notes
SSH	Behaviour model	CLI transport and authentication outcome.
HTTP	Behaviour model	Simple service/wire handling for supported tests.
TFTP	Behaviour model	File-transfer executor/wire surface.
SCP	Behaviour model	Secure-copy style transfer surface.
File-system view	Config-backed	IOS-style/NX-OS-style show file systems exposes deterministic simulator file systems.
TCP/UDP handlers	Behaviour model	Support protocol tests; not a full OS socket stack.

Standards coverage

Standard	Coverage	Notes
SSH	Behaviour model	Login/session outcome, not cryptographic transport.
HTTP/1.x	Minimal	Request/response service behaviour.
RFC 1350	Partial	TFTP transfer concepts.
SCP	Minimal	Operational file-copy model.

Feature matrix

Feature	Status	Notes
VTY login	Supported	Uses local/AAA auth outcomes.
SSH reachability	Supported	Depends on routing, ACL, and service state.
HTTP service	Behaviour model	Simple responder.
TFTP copy	Behaviour model	Supported executor path.
SCP copy	Behaviour model	Supported wire path.
Source interface	Partial	Supported where command surface exposes it.

Vendor command matrix

Command	IOS-style	Junos-style	VyOS-style	Notes
ip ssh version 2	Supported	Partial	Partial	SSH service intent.
line vty 0 4	Supported	n/a	n/a	Remote CLI access.
transport input ssh	Supported	n/a	n/a	SSH-only VTY.
ip http server	Supported	Partial	Partial	HTTP service.
show ip http server	Supported	n/a	n/a	IOS/IOS-XE runtime service view.
show tftp	Supported	n/a	n/a	IOS/IOS-XE runtime service view.
show file systems	Supported	n/a	Supported	IOS/IOS-XE and NX-OS-style file-system view.
copy tftp: running-config	Partial	n/a	Partial	TFTP operation.
copy scp: flash:	Partial	n/a	Partial	SCP operation.

Behaviour notes

Management protocols are primarily reachability and authorization checks. If an ACL blocks TCP/22 or AAA denies the user, the management operation fails for that reason.

Examples

Canonical example

configure terminal
username admin privilege 15 secret lab
ip ssh version 2
line vty 0 4
 login local
 transport input ssh
end

Vendor styles

IOS-style

username admin privilege 15 secret lab
ip ssh version 2
line vty 0 4
 login local
 transport input ssh

Junos-style

set system services ssh
set system login user admin class super-user authentication plain-text-password
set system services netconf ssh

VyOS-style

set service ssh port 22
set system login user admin authentication plaintext-password lab

Known limits

Real SSH crypto negotiation, HTTP feature completeness, binary file contents, TFTP retransmission timers, and platform filesystem quirks are simplified.
