Release Notes v 1.0 Page 57 of 79
Defect ID:
DEFECT000400771
Technical Severity:
Medium
Summary:
If the usage of TCAM entries reaches near the maximum, a route entry could be overwritten by
another route entry.
Symptom:
Routed traffic may not be forwarded to directly connected hosts in rare instances if the TCAM usage
reaches near its maximum limit.
Workaround:
Clear the ARP cache and MAC table, then disable and re-enable the relevant IP interface.
Probability:
Low
Feature:
FCX Layer 3 Forwarding - IPV4
Function:
Data Forwarding (IPV4)
Reported In Release:
FI 07.3.00
Service Request ID:
728137
Defect ID:
DEFECT000401082
Technical Severity:
High
Summary:
Cannot communicate with Tagged Promiscuous port on Primary VLAN from Isolated VLAN over
PVLAN-trunk.
Symptom:
When the Promiscuous port in the Primary VLAN is Tagged, an ARP request may be forwarded with
an incorrect VLAN tag.
Workaround:
Use Untagged port on Primary VLAN.
Probability:
Medium
Feature:
FI L2
Function:
Forwarding - Private VLAN
Reported In Release:

Defect ID:
DEFECT000402371
Technical Severity:
High
Summary:
The "system-max hw-ip-route-tcam" CLI command should be blocked for FCX platform.
Symptom:
The "system-max hw-ip-route-tcam <number>" command is not relevant for FCX platform but is still
accepted. If it is mistakenly configured, it can cause a side-effect where some routes are prevented
from being programmed in the TCAM, thereby causing IP connectivity loss.
Workaround:
Remove the "system-max hw-ip-route-tcam <number>" command from FCX configuration, save
the configuration and reload the router.
Probability:
Medium
Feature:
FCX Layer1 features
Function:
System-max parameters

Defect ID:
DEFECT000403066
Technical Severity:
Medium
Summary:
If a router is upgraded directly from 4.x code version to 7.2, SSH access to the device could result in a
system reset.
Symptom:
If a router is upgraded directly from version 4.3 to 7.2 or later code without regenerating the SSH key,
the system may reset if an SSH access is attempted.
Workaround:
1. Invoke the “crypto key gen” command to regenerate the key after the upgrade.
2. Upgrade the device first from version 4.x to 7.1, and then upgrade it from 7.1 to 7.2 or later code
streams.
Probability:
Medium
