z
When PPPoE over LAG is configured on an interface, and you re-execute the
PPPoE-over-LAG configuration before you delete the previous configuration, the ES2
10G LM line module resets. [Defect ID 179639]
Work-around
: Before you can re-execute the PPPoE-over-LAG configuration, delete
the existing PPPoE-over-LAG configuration.
z
Specifying S-VLAN ranges that partially overlap does not work. [Defect ID 81918]
For example, the following configuration fails because S-VLAN 22 falls within the
previously specified S-VLAN range of 21–23.
host1(config-if)
#
vlan bulk-config BulkDHCPCnfg1 svlan-range 21 23 401 426
host1(config-if)
#
vlan bulk-config BulkDHCPCnfg1 svlan-range 21 23 427 712
host1(config-if)
#
vlan bulk-config BulkCezarCnfg2 svlan-range 22 22 101 110
Work-around:
You can do either of the following to avoid this problem.
−
Specify each S-VLAN within the partially overlapping range as individual
S-VLANs, as in the following example:
host1(config-if)
#
vlan bulk-config BulkDHCPCnfg1 svlan-range 21 21 401 426
host1(config-if)
#
vlan bulk-config BulkDHCPCnfg1 svlan-range 22 22 401 426
host1(config-if)
#
vlan bulk-config BulkDHCPCnfg1 svlan-range 23 23 401 426
host1(config-if)
#
vlan bulk-config BulkDHCPCnfg1 svlan-range 21 21 427 712
host1(config-if)
#
vlan bulk-config BulkDHCPCnfg1 svlan-range 22 22 427 712
host1(config-if)
#
vlan bulk-config BulkDHCPCnfg1 svlan-range 23 23 427 712
host1(config-if)
#
vlan bulk-config BulkCezarCnfg2 svlan-range 22 22 101 110
−
Use fully overlapping ranges rather than partially overlapping ranges, as in the
following example:
host1(config-if)#
vlan bulk-config BulkDHCPCnfg1 svlan-range 21 23 401 426
host1(config-if)#
vlan bulk-config BulkDHCPCnfg1 svlan-range 21 23 427 712
host1(config-if)#
vlan bulk-config BulkCezarCnfg2 svlan-range 21 23 101 110
z
When you attach certain hierarchical policies to subinterfaces as input policies,
secondary input policies, and output policies, incoming traffic loss can occur when
the number of subinterfaces to which the policies are attached exceeds 4600.
[Defect ID 86741]
z
Ethernet statistics are incorrectly displayed for virtual port 8 of the ES2-S1 GE-8 IOA
when that module is paired with the ES2 10G LM or the ES2 10G Uplink LM. [Defect ID
174784]
z
The ES2 10G LM does not support framed routes configured for dynamic subscriber
interfaces. [Defect ID 83154]
z
On the ES2 10G LM, a VLAN ID of 0 assigned to an interface can prevent packets from
being properly forwarded. [Defect ID 176125]
ICR
z
If you saved the running configuration of the router as a script file (.scr) and execute
the script to apply the settings on the router, ICR partition configuration commands
in the .scr file might fail to add group members to the partition. This problem happens
when the subscriber configuration in the .scr file is placed before the ICR partition
configuration. However, this problem does not occur if you used a system
configuration (.cnf) file to set up the router. [Defect ID 183913]
