VOSS / EXOS command translator

A side-by-side reference between VOSS (Fabric Connect / SPBM) and EXOS. Search a task or command to see how each CLI expresses it - and where EXOS has no equivalent.

Documentation

A reference, not a config generator. EXOS does not run SPBM; it joins a fabric as a Fabric Attach edge.

Enter configuration mode
VOSS
enableconfigure terminal
EXOS
configure ... (runs directly)

EXOS has no separate enable / configure-terminal step; configuration commands run straight from the top prompt.

Create a VLAN
VOSS
vlan create 20 type port-mstprstp 0
EXOS
create vlan v20 tag 20

In VOSS the VLAN stays local to the edge; the fabric carries the service by its I-SID (see the Layer 2 VSN row).

Add ports to a VLAN
VOSS
vlan members add 20 1/1
EXOS
configure vlan v20 add ports 1 untagged

VOSS ports are slot/port form (1/1); EXOS uses a port list. Use tagged instead of untagged for a trunk / uplink port.

Map a VLAN to a fabric service (Layer 2 VSN / I-SID)
VOSS
vlan i-sid 20 20020
EXOS
configure fabric attach port 1 authentication enableconfigure vlan v20 add ports 1 tagged

EXOS does not create I-SIDs. As a Fabric Attach edge it signals the VLAN on its uplink, and the VOSS FA Server provisions the matching I-SID into the fabric.

Build the SPBM fabric core (area, nickname, B-VLANs, system-id)
VOSS
router isismanual-area 49.0000spbm 1spbm 1 b-vid 4051,4052 primary 4051spbm 1 nick-name c.65.01system-id 020c.0650.0001router isis enable
EXOS
No direct equivalent - EXOS does not run SPBM.

No equivalent: EXOS does not support SPBM. It joins the fabric through Fabric Attach instead of becoming a fabric node.

Enable IS-IS / SPBM on a fabric (NNI) uplink
VOSS
interface GigabitEthernet 1/49isisisis spbm 1isis enable
EXOS
No direct equivalent - EXOS does not run SPBM.

No equivalent: VOSS runs IS-IS only on fabric NNI links. On EXOS the uplink to the fabric is a Fabric Attach port (see the Fabric Attach row).

Fabric Attach at the edge
VOSS
fa enable
EXOS
enable sharing 1 grouping 1-2configure fabric attach port 1 authentication enableconfigure fabric attach ports 1 authentication key <key>

VOSS runs the FA Server; EXOS runs the FA Proxy/Client. FA rides LLDP, and the Server auto-provisions the I-SID from the edge VLAN. The sharing/grouping line is only for a LAG uplink.

Layer 3 VSN (a routed service across the fabric)
VOSS
ip vrf 1 vrfid 1router vrf 1ipvpni-sid 20010ipvpn enable
EXOS
No direct equivalent - EXOS does not run SPBM.

No equivalent: EXOS does not run L3 VSN. To exchange IP routes with the fabric, redistribute OSPF, BGP, or RIP across the boundary.

Verify the service
VOSS
show i-sidshow isis spbm i-sid allshow vlan i-sidshow fa elements
EXOS
show fabric attachshow vlanshow ports

On VOSS you verify the I-SID in the fabric; on EXOS you verify the Fabric Attach state and the VLAN.
