New and Enhanced Software Features
There are no new software and hardware features introduced in Cisco NX-OS Release 9.3(9). The following table lists the enhancement done in Cisco NX-OS Release 9.3(9).
| Enhancement |
Description |
| Cisco QSFP-100G-DR-S Module Support |
Added support for Cisco Nexus 3232C platform switches. For more information see, Cisco Nexus 3000 Series NX-OS Interfaces Configuration Guide, Release 9.3(x). |
Note: Cisco Nexus 3000 series do not support one-step PTP.
| Bug ID |
Description |
| Headline: Nexus 3500 : Output discard due to buffer drops not reported for SPAN oversubscription. Symptoms: On Nexus 3500, output discards caused by buffer drops are not incrementing on the span destination port. Workarounds: None |
|
| Headline: The “ipv4 routing multicast holddown" is not working as expected on Nexus 3500. Symptoms: 1. Holddown time of 0 is not disabling timer after reload for both non-xl and xl box. 2. disable-init-phase on XL is getting changed to 0 in running config and again not disabling timer after reload. Because of which traffic convergence is higher than expected. 3. disable-init-phase is working fine on non-xl box but the option is hidden. Workarounds: None |
| Bug ID |
Description |
| Headline: N3500 interfaces may stop processing rx traffic after connected host NIC flaps Symptoms: N3500 interface rx counters are not incrementing. Workarounds: Reload ascii of N3500. |
|
| Headline: Nexus 3000 switches cannot form IS-IS adjacency over vPC Peer-Link Symptoms: Nexus 3000 series switches that are configured to form an IS-IS adjacency between two vPC peers across the vPC Peer-Link will not successfully form an IS-IS adjacency between each other. Workarounds: Create a dedicated Layer 3 connection between vPC peers and form IS-IS adjacencies over the dedicated Layer 3 connection instead of forming the IS-IS adjacency across the vPC Peer-Link. |
|
| Headline: Nexus 3548 ACL dropping initial fragmented UDP packet. Symptoms: When configuring an ACL on a L2 or L3 interface to permit fragmented traffic, if the protocol is UDP, the first/initial-fragment is dropped. Workarounds: Change the ACL statement to "ip" instead of "udp". |
|
| Headline: IPv6 LLA BGP control packets matching Default CoPP class on N34XX-S based platforms Symptoms: Add support for IPv6 link local BGP peering. Workarounds: None |
