Known Problems and Limitations
Forwarding
The DoS protection egress rate is not accurate for the ES2 10G LM or the ES2
10G Uplink LM. [Defect ID 86925]
When performing MAC validation to match subscriber demux entries with ARP
host entries, the ES2 10G LM does an exact match, rather than a longest prefix
match. The subscriber demux entry source address must be a /32 value
matching the IP address of an ARP entry in order to validate the MAC address
against that ARP entry. [Defect ID 79641]
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.
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]
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]
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)#vl
an 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
