Limitations and Restrictions on the Cisco ASR 920 Series Routers

  • The default interface command is used to default the parameters under that interface. However, when speed is configured on the interface, the following error is displayed:
Speed is configured. Remove speed configuration before enabling auto-negotiation
 
  • SSFPs are not supported on the Cisco ASR-920-24SZ-IM, ASR-920-24SZ-M, ASR-920-24TZ-M, and ASR–920-12SZ–IM Aggregation Services Routers.
  • Adding or deleting the Trunk Ethernet flow points (TEFPs) with scaled bridge-domain, without delay causes the Cisco ASR920 Series router to crash. This issue occurs in Cisco IOS XE Release 3.1.3.0S and later.
  • In the case of power loss on the Cisco ASR-920-24SZ-IM, ASR-920-24SZ-M, ASR-920-24TZ-M Aggregation Services Routers running Cisco IOS-XE Release 3.14.0S and the Cisco ASR-920-12SZ-IM running the Cisco IOS-XE Release 3.16.1aS, dying gasp packets are sent to peer routers. However, the system state is not captured in the system logs (syslogs) or SNMP traps.
  • Interface naming of the Cisco ASR-920-12SZ-IM is from right to left. For more information, see the Cisco ASR 920 Series Aggregation Services Router Chassis Configuration Guide.
  • Virtual services should be deactivated and uninstalled before performing replace operations.
  • Effective Cisco IOS-XE Release 3.18S, packet size greater than 1460 is not supported over IPsec Tunnel for ASR-920-12SZ-IM.
  • For ASR-920-12SZ-IM, minimal traffic drop might be seen for a moment when higher rate traffic is sent through the IPsec tunnels for the first time.
  • Effective Cisco IOS-XE Release 3.18S, IPsec is only supported for TCP and UDP and is not supported for SCTP for ASR-920-12SZ-IM.
