2. General 

1. How to check the arp when the satellite has auto ip configured?

sh arp vrf **nVSatellite

 

RP/0/RSP1/CPU0:9K-MSN1#sh arp vrf **nVSatellite

Yes. For eg. Ten 1/45 is using 1G SFP while ten1/46 is using 10G SFP

 

19.  Can 10G port on the 901-AC-10G chassis be used as ICL?

No, the 10G ports can neither be used as ICL nor as Access ports in 5.1.1 release

 

20. How to debug if there is an issue with satellite specific traffic drops?

Please debug the drops on the satellite using https://supportforums.cisco.com/docs/DOC-40094#Ping_or_Data_Packet_Drop_on_Host

 

21. The satellite crashed while doing some config changes. How to debug this?

Collect the crashinfo dumped in the flash of the satellite. Decode the traceback and involve the appropriate team to triage this further.

4. Can we have sat-ether bundle with members spanning from different satellites in a ring?

The configuration is not blocked but since satellites can be active/Stby on different hosts, they cannot be bundled in a single bundle effectively.

 

5. How to check if isolation recovery delay timer  is running when the backbone interface/ICCP interface is brought back UP with PE isolation feature configured?

Check the output of “show iccp group <iccp_group_num>

6. Is bundle ICL supported on Simple Ring  topology?

No

 

 

7. Is ASR901 AC model supported and can be used in Simple Ring in 5.1.1 release?

Yes, ASR901 AC model is supported. But only 1G ports are used for both ICL and access ports testing on 5.1.1 release.

 

8. Is auto Ip supported on Simple Ring?

Yes

 

9. What are the different states the sats go to during redundancy switchover and during icpe_satmgr process restart in Simple ring setup? Will there be any traffic drop at that time?

During redundancy switchover/icpe_satmgr process restart, the active satellites on that host go to connecting and then to connected state.

The standby satellites on that host goes to configuring, and then to connected state. The configuring/connecting changes are all expected. This is because  there is a temporary split brain scenario, which causes the TCP  session to be re-established. The split brain scenario has different impact on the Active and the Standby hosts.

 

There is a possibility of temporary traffic drops for 1-2 secs.

 

10. How is the active/standby host selection done in case of Simple Ring? What all aspects are considered for this election?

The following 5 criterion are considered for the active/standby host selection:

    • "connectedness" - to be considered connected, SDAC discovery must be up and SDAC control must have come up at some point (it does not have to be up permanently, as we don't want TCP flaps to cause failover)
    • PE-isolation
    • user-configured priority
    • number of hops
    • tie-break (odd/even numbered satellites)

 

11. I did install nv satellite activate for all satellites in ring, but some satellites did not boot up with latest image

For Ring first issue “install nv satellite transfer all” and wait for image to be transferred successfully to all satellites(show nv sat status brief). Then execute “install nv satellite activate”.

 

12. Is port partitioning supported in Simple Ring?

No

 

4. Dual Home

1. How to check if the ICCP group is up or not in Dual Home?

Check the output of “show iccp group <iccp_group_num>” which gives the details.

 

2. How to check if the orbit has come up or not in Dual Home>

Check the output of “show nv satellite protocol redundancy” which gives the details.

 

3. What are the limitations with respect to satellite Dual-home pairing?

A satellite  can only be connected to two hosts

A host can only be in one dual-home pairing

 

4. Is port partitioning supported in Dual Home?

Yes

 

5. What would be the IP addresses for Active and Standby in case of DH topology with auto-ip?

Active host will have 10.0.0.1 and Standby-host will have 10.0.0.2

 

6. Is bundle ICL supported on Dual Home  topology?

Yes

7. Does satellite automatically reroutes to standby host incase of Primary host failure. How much time does it takes for traffic convergence?

The satellite automatically reroutes to the other ASR9K host incase of Primary host failure. We should see sub-second convergence for L2 traffic. For L3 the convergence will be dependent on the routing protocol.

8. Does the satellite reverts back to the active host incase the active host comes back up after failure.

      Yes. The satellite reverts back to the active host incase the active host comes back up after failure. Please note that the satellite status on the active host should be "Connected", otherwise the satellite will not revert back to the Previous Active host.

9. For PE Isolation switchover, will a Dual home switchover be triggered if the backbone interface was still up and only the IGP goes down for some reason ?

    No, the PE isolated DH switchover only triggers when the link goes down physically or is administratively shut on the Active Host . It is not triggered if  the IGP goes down on the backbone interface but the link is up .

5. L2 Fabric

 

1. What is the configurable VLAN range on the L2fab link in case of  ASR9000v/ASR901  platform?

9000v: 4092 (VLAN 1 & 4094 are reserved for internal usage)

901: 4093 (VLAN 1 is reserved for internal usage)

 

2. What are the encapsulation types supported on L2Fab links?

802.1q & 802.1ad

 

3. Is bundle ICL supported in L2fab topology?

No

 

4. Is auto-IP supported in L2fab?

Yes

 

5. Is Dual Home supported in L2fab?

Yes

 

6. Is port partitioning supported in L2fab?

No

 

7. Is CFM on ICL link mandatory for L2FAB?

No , but without CFM convergence for DH SO will be very slow(>30 secs). To achieve subsec convergence it is recommended to use CFM on the ICL link

 

8. Can we use same VLAN ID on both Hosts in L2fab-DH topology?

Yes, but only when 2 physical ICL links are used on SAT where each ICL is mapped to different hosts. Refer to L2FAB supported topologies

 

9. What is the VLAN-ID  and encap-type to be used in case of single ICL link on SAT?

In case of single ICL on SAT we need to make sure different VLAN ID and same encapsulation type are used on the L2fab links on Hosts

 

10. Can we use different encap-type on the L2fab links on Hosts in L2fab-Dual Home topology?

Yes . But make sure 2 physical ICLs are used on SAT, one for each Host.

12.     How to verify Satellite IP config from Satellite?

Note: Tengig1/45 is the ICL. Gig0/4 & gig0/5 are CPU ports on which is the actual satellite ip get configured. Since this is Dual Home topology we see 2 CPU ports are configured with the same satellite ip address.

Hi Carlos,

 

Yes, the host's loopback IP address should be different on the two hosts. However the IP address for satellite should be the same.

Thanks,

Santosh

Hi

 

You're listing in the document here that the following is not supported:

 

The following topology options are not supported:

    • Simple Ring with both ends terminating on same host

 

Is there a plan for supporting simple ring with both ends terminating on the same host instead of dual host? I see it is not available in 5.1.3 and it seems not to be available in 5.3.1.

It this support on the roadmap? If so, when?

Thanks.

Hi Guys

I'll like to find out if it possible to deploy the satellite cards to a remote location (approximately 70 KM) from the host using L2 service from ISPs with bandwidths 100 Mb/s to 1Gb/s?

Cisco Employee

yes, you can do that, see:

"Layer 2 Fabric" is a characterisation of the ICL. It doesn't imply that the satellite (sub)interfaces must be l2transport.

These two lines are optional:

ipv4 point-to-point
ipv4 unnumbered Loopback0

We recommend the auto IP assignment on ICL.

regards,

Aleksandar

Hi, Aleksandar:

Do you have a quick configuration example of auto-ip? I would like to test it and to know what to look for if we decide to use it.

Thanks,

c.

Cisco Employee

hi Carlos,

simply eliminate the ipv4 config commands from the ICL and the system will automatically assign an IPv4 address from the predefined vrf named **nVSatellite .

You don't really need to know the IPv4 address on the ICL nor the vrf name because the show commands should give you lots of info without connecting to satellite via telnet. Even if you need to telnet to the satellite, you can use "telnet satellite <number>", which will resolve for you the vrf and IPv4 address.

regards,

Aleksandar

Good morning..

 

I can't find any specific reference for this, but I was wondering if a pair of 9001 hosts could support two simple rings, as seen below?  I've seen diagrams with a simple ring and then a daisy-chained line of 9000v, but not this specific configuration.  I have customer replacing a ring (Cisco 10K's) with the ASR's, using the 9001's at the intersection of another ring, so placement of the 9001's is fixed.. 

 

Thank you..
