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.

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:
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
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 .
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.

Hi, All:
Quick question: for a dual-home environment, when the active linkA goes down from sat-to-hostA, the standby linkB from sat-to-hostB takes over. What is expected to happen when linkA recovers. What we've seen is that it doesn't revert back to linkA. Is there a way to control this and force a 'revertive' behavior? What would be the command for 5.1 to enforce this in case it can be controlled?
Thanks,
c.
Hi Carlos,
By default the satellite will revert back to the active Link once it comes back up. Can you please verify the configs on the hosts.

Hi Carlos,
Thanks a lot for sharing the running config. The configs looks fine, the satellite should revert back to the active host once the Active hosts comes back up.
We need to debug it further. Can you please collect: "show tech satellite", "show iccp group <>", "show nv sate stat" from both the hosts after the Active host comes up.
Thanks,
Santosh
Hi, Santosh:
i opened a Tac SR and they said what I'm seeing is normal behavior. They said user configured priority is only used by satellite on bootup.
now, i'm confused.
c.
Hi Carlos,
Please share the SR# opened to track this. We will take a look.
Thanks,
Santosh
Hi, Santosh:
SR is 634258869.
there you can find my email address. Please share any findings you come to. Also, I added a few questions to the SR a little late that have not been answered.
thanks,

Hi,
what is the maximum number of ASR9000V satellites that can be connected to a single ASR9K and ASR9K cluster, in Hub & Spoke mode ?
Rgds
Harin
Hi Harin,
At present we support 64 satellites for H&S mode. The number is same for both cluster and non-cluster nodes.
Hi Carlos,
I had a look at the logs. The satellite will revert back to the active host only if the satellite's state is "Connected" on the active host. We need to check why the satellite is stuck in "Connecting" at the Active host.
I think other Qs are already answered in the SR itself. Let me know if any Q is outstanding.
Thanks,
Santosh
Hi, Santosh:
Now I'm really confused, because what TAC says is that I have 'normal' behavior. What I gather from the first part of your post is that something is in fact wrong with my setup and that I should follow up with TAC. If so, could you point that out to the TAC engineer in charge of my SR?
Thanks,
c.
Santosh:
Just as a follow up: I have the 'connected' status in the active host, always have.

Hi, Santosh:
Sorry for hogging the comments, but I wanted to ask you the following: my setup initially had all SATs connecting to one single host. Then customer started dual-homing them.
Since we had single-host connection we used a single IP address and the same Ip address for all hosts (9010, as ip unnumbered loopback). I'm not using auto-ip.
If using static ip addressing on all SATs and having, at least one dual-homed, should the host ip be different in both active and standby hosts? also, should i configure the static ip address of the DH sat differently in both the active and standby host (or can it stay the same)?
Thanks,
c.
Hi Carlos,
