Known Issues, Platform-Specific, and Feature Change Requests (CRs)

CR Number Description
General
xos0071238 Due to upgrading ExtremeXOS 30.1 to 4.14 Linux kernel, ping success to local IP addresses does not depend on link-layer status. Earlier releases of ExtremeXOS had customized Linux behavior that meant that pinging a local VLAN interface would fail when the local interface was down. However, in ExtremeXOS 30.1, pinging a local VLAN interface that is down will result in a successful ping.
xos0071351 When a network is unreachable, switches return ICMP host unreachable packets instead of ICMP network unreachable packets.
ACLs
xos0073140 Clearflow counters work when ACLs are applied to VLANs, but not if applied to ports or wildcards.
xos0072272 For VXLAN tunnel endpoints (VTEPs), the following ACL match conditions/actions do not work:
  • Destination MAC and Source IP match condition combination
  • Source MAC and Destination IP match condition combination
  • Redirect-port-list action
Extended Edge Switching
xos0073364 Extended port LAGs cannot be present in VXLAN tenant VLANs.
xos0073328 Extended ports cannot be untagged members of VXLAN tenant VLANs.
