Restrictions for Smart SFP
![]() Warning |
If MR-APS is configured on the SFP, then remove MR-APS configuration before you remove the SFP from the port. |
-
CEM interface configuration isn’t supported.
-
The following default attributes are available only under CEM interface configuration. But you can't configure these attributes, as the configuration CLIs aren’t supported.
-
dummy mode
-
dummy pattern
-
idle pattern
-
-
E1 emulation is supported only on Ethernet pseudowire (VPWS).
-
CSoP doesn’t support E1-AIS alarm.
-
No support to Single Router–Automatic Protection Switching (SR-APS)
-
CLI configuration for the E1 controller on a VLAN needs to be mapped to an Ethernet sub-interface (by configuring same VLAN dot1q under the sub-interface). Any xconnect, also must be configured with this ethernet sub-interface.
-
Multi Router-Automatic Protection Switching (MR-APS) is supported only by using the VLAN PW.
-
Ensure that you have more than one MPLS paths, in core to convergence during core failure scenario.
-
Only 8 smart SFPs are supported per router.
-
ACR clocking is not supported in TPoP and CSoP unframed SFPs. Only framed to framed connection is supported, so not supported on framed to unframed connections.
-
STM1 CSoP:
-
E1 Level shutdown is not supported.
-
Controller shutdown won’t inject AIS but injects only LOS towards CE.
-
Bit error rate test (BERT) can be run only on one E1 channelized controller.
-
-
CSoP and TPoP:
-
25G ports are not supported.
-
Bit error rate is not supported.
-
-
SF or SD threshold is not supported.
-
Only 16-byte J0 is supported.
-
BERT is not supported in unframed SFP.
-
Loopback is supported only on, one of the 63 channels of CSoP SFP.
-
Configuration with same ECID for CSoP E1s is not supported. ECID must be unique for each E1 under CSoP.
-
The show alarm conditions command is not supported in Release 7.5.1.
-
High convergence of 100ms is observed for MR-APS for LOS based switchover (for CSoP E1s).
-
With smart SFP, high convergence of 4-6 minutes is observed in MR-APS for router reload based switchover.
-
CSoP loopback on framed STM1-ch E1 doesn’t work over reload warm command with smart SFP. Applicable only in Release 7.5.1.
-
FPD upgrade for smart SFP is supported only from Release 7.8.1.
-
LCV counter updates are not supported for smart SFP.
