Resolved Bugs

Table 1 Resolved Bugs in Cisco NGA 1.0 (3)
Identifier
Description

CSCum63633

NGA 3140 flow timestamp is incorrect.

In Cisco NGA, if a flow consists of a single packet, the exported value of the last timestamp may be one tick less than the value of the first timestamp. To avoid this incorrect timestamp, the configuration must be done in such a way that the first timestamp is updated before the last timestamp.

CSCum68945

Target libxml2 needs to be updated.

CSCuq98883

Cisco NGA software does not show CLI idle timeout.

CSCur19649

Upgrade the NGA image to CiscoSSL.

CSCur28244

Add new CLI command to allow you to remap ifDescr, ifName, and ifAlias strings.

CSCur59609

The data port is not shut down when unused.

CSCur61498

Cisco NGA evaluates the SSLv3 POODLE vulnerability in CBC mode.

CSCur70752

CSCur95485

Secure file transfer is unsupported.

CSCtx28541

Cisco NGA does not work with TACACS+ server.

CSCuq86459

TLS1.1 is unsupported.

CSCus14910

Cisco NGA reduces the maximum value of cache size from 80M to 72M on NGA 3140 and 3240. This cache size reduction avoids low memory issue. NGA 3340 has 80M cache size.

Table 2 provides a list of resolved bugs in Cisco NGA Software Release 1.0 (2) Patch 2.

Description

CSCup32818

Cisco NGA does not handle FABRICPATH packets correctly.

If traffic is directed to the NGA data ports which have Fabricpath encapsulation, the traffic may not be accounted correctly. The Cisco NGA exports incorrect flow values for MAC addresses, ethertype, and other fields.

CSCup45836

The show lookup statistics command shows only the number of successful lookups and the number of failures. This command does not classify separately the number of times the lookup was not even attempted due to broadcast/multicast MAC address.

CSCup89904

Critical third party packages are not upgraded.

CSCup90747

The frequency of logins to remote device(s) is more.

CSCup32912

Cisco NGA returns incorrect values for some SNMP MIB objects.

CSCup90918

In HSRP deployments, traffic that is switched through "Gateway" MAC address must be associated with the VLAN SVI interface instead of the port-channel connecting the peer switches.

CSCur64313

Cisco NGA logs incorrect error messages in nam_debug_log.txt file for debugging purpose.

Table 3 provides a list of resolved bugs in Cisco NGA Software Release 1.0 (2) Patch 1.
