nV Satellite Remote Access for Management

[james.munroe]

Hello Folks,

Is it possible to remotely manage 9000V nV satellite units from networks outside the ASR9K host(s)?

Local access to the respective 9000V Sats works fine...however from networks outside of the NV management Lo the nV Sat's IP is not accessible.

Just looking for a sanity check.  Running IOS-XR 5.3.1 w/ latest SMU's.

Thanks In advance!!

ASR9K Config:

interface Loopback102
 description nV Satellite Mgmt Interface
 ipv4 address 10.0.0.1/24

!

interface Bundle-Ether102
 description SID#102
 ipv4 point-to-point
 ipv4 unnumbered Loopback102
 nv
  satellite-fabric-link satellite 102
   remote-ports GigabitEthernet 0/0/0-43

!

nv
 satellite 102
  type asr9000v
  ip address 10.0.0.2
  description * SID102 *
  device-name SID102
 !

Examples:

RP/0/RSP0/CPU0:PE1#ping 10.0.0.2
Thu Oct 22 13:20:30.502 ADT
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.0.0.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms

RP/0/RSP0/CPU0:PE1#ping 10.0.0.2 source 10.10.10.1
Thu Oct 22 13:21:05.286 ADT
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.0.0.2, timeout is 2 seconds:

Success rate is 0 percent (0/5)

hi James,

We have introduced satellite usability enhancements in 5.3.2, some of them added more to "show nv satellite" commands to further limit the need to telnet to the satellite.

We don't allow telnet to satellite from remote devices, it kind of beats the purpose of the satellite.  In case you still need to telnet to a satellite, from 5.3.2 you can use the satellite number:

RP/1/RSP0/CPU0:nv-cluster-escalation#telnet satellite ?
  <100-65534>  Connected Satellite
  vrf          Manually specify a VRF and IP address to a satellite

hth,

Aleksandar

Hi Aleksandar,

Thank You for the prompt answer!  It was for the purpose of IPAM and NMS Ping for health...not remote management as in telnet/ssh.

So with that said, one final question.  In my example above:

interface Loopback102
 description nV Satellite Mgmt Interface
 ipv4 address 10.0.0.1/24

What is the best practice for the nV Satellite loopback mask?  /32?

Thanks in Advance!

Jim

hi Jim,

we actually recommend to use auto-ip for address assignment. If you prefer manual config, the mask on the loopback should be short enough to accommodate for one IP address per connected satellite.
