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)#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
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]
The ES2 10G LM does not support framed routes configured for dynamic
subscriber interfaces. [Defect ID 83154]
A memory leak of about two percent can occur on the ES2 10G LM and result in
a module reset when a large number of successive SRP switchovers take place
with active DHCP clients. [Defect ID 86245]
On the ES2 10G LM, a VLAN ID of 0 assigned to an interface can prevent
packets from being properly forwarded. [Defect ID 176125]
