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.
VPLS forwarding does not function properly when any of the following
conditions occur: [Defect ID 79856]
MLPPP interfaces are used
L2TP is used with sequence numbers enabled
GRE is used with sequence numbers enabled
Specifying S-VLAN ranges that partially overlap does not work. [Defect ID
81886/81918]
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
