Last Modified: Sep 13, 2023

Affected Product(s):

Known Affected Versions:
11.6.1, 11.6.2, 11.6.3, 11.6.3.1, 11.6.3.2, 11.6.3.3, 11.6.3.4, 11.6.4, 11.6.5, 11.6.5.1, 11.6.5.2, 11.6.5.3, 12.0.0, 12.0.0 HF1, 12.1.0 HF1, 12.0.0 HF2, 12.1.0 HF2, 12.0.0 HF3, 12.0.0 HF4, 12.1.1 HF1, 12.1.1 HF2, 12.1.2 HF1, 12.1.2 HF2, 12.1.0, 12.1.1

Fixed In:
13.0.0, 12.1.2

Opened: Jun 17, 2016

Severity: 3-Major

Symptoms

Packets arriving on members of the VLAN group are CMP redirected. Redirections may be tracked with the tmm/flow_redir_stats table.

Impact

Throughput drops because of the redirections. However, because this is an error in the software disaggregator, components and features which depend on correct disaggregation may fail. Some features of PEM may fail.

Conditions

VLANs in the VLAN group must have different cmp-hash settings. For example, one VLAN may configure src-ip and another dst-ip.

Workaround

None

Fix Information

Packets are correctly disaggregated without redirections.
