Level: 3 Ports on the SwitchBlade and AT-9800 are now initialised to advertise pausing as disabled. PCR: 03606 Module: IPG Level: 2 BGP and UPNP were not informed when an ETH interface went up or down. This issue has been resolved.

PCR: 03717 Module: IP, SWCX Level: 2 New static routes cannot be added to the forwarding database until ARP has resolved the routes' next hop MAC address. In the meantime, selecting the best alternative route was sometimes causing incorrect

6 Patch Release Note PCR: 03795 Module: SWI Level: 3 Browsing the dot1dTpFdbPort table with SNMPv2c sometimes gave incorrect output. This issue has been resolved. PCR: 03796 Module: STP Level: 2 Setting RSTPTYPE to NORMAL, when normal has already been set, sets all ports to the “sending RSTP” state process. This is referred to in IEEE 802.1w as mCheck. When RSTPTYPE was changed from STPCOMPATIBLE to NORMAL with the SET STP co

Patch SB251-13 For SwitchBlade 4000 Series Switches and AT-9800 Series Switches 7 PCR: 03817 Module: IPV6 Level: 2 A fatal error occurred when IPv6 fragmented a packet. Also, when a large fragmented ICMP echo request packet was received, the reply may not have been fragmented and so may have exceeded the MTU for the interface it was sent on. These issues have been resolved. PCR: 03819 Module: SWCX Level: 3 Previously, Multicast

This issue has been resolved. PCR: 03835 Module: VLAN Level: 3 If either the MCLIMIT or BCLIMIT parameter in the SET VLAN MCLIMIT BCLIMIT command was set to NONE, the other parameter was sometimes incorrectly set to NONE as we

This issue has been resolved. PCR: 03913 Module: SWCX Level: 2 A fatal error occurred with NVS when the log contained too many debug log messages. These messages were added with PCR 03701. This issue has been resolved. P

12 Patch Release Note Prefixes of Anycast addresses could not be shared on the same port. This issue has been resolved. PCR: 3956 Module: SWI, CORE Level: 2 On an AT-9800 with certain third party GBICs, running the restart reboot command would cause the switch to lock-up. However the problem did not occur when using the Reset button. This issue has been resolved by disabling all ports before performing a RESTART REBOOT. PCR: 03965 Module: IPSEC

Patch SB251-13 For SwitchBlade 4000 Series Switches and AT-9800 Series Switches 13 PCR: 031003 Module: QOS Level: 3 The SET QOS VLANREMAP command was incorrectly saving configuration files. This was resulting in errors occurring when the file was executed. This issue has been resolved so that the file is saved in the correct form. PCR: 031005 Module: SWCX Level: 3 CAM errors were appearing when the ENABLE SWITCH BIST command was r

14 Patch Release Note BIST failures were occurring because the software was not full supporting the SwitchBlade 8 port 1000BASE-LX line card 1 (AT-SB4462). This issue has been resolved. PCR: 031033 Module: Level: 2 STP was not being handled correctly when hot swapping line cards. This resulted in links other than the preferred link being selected. Also, when a layer two data stream was forwarded from one line card (the source card) to another (the destination

Patch SB251-13 For SwitchBlade 4000 Series Switches and AT-9800 Series Switches 15 Multicast Listener Discovery Snooping Multicast Listener Discovery (MLD) snooping enables the switch to forward IPv6 multicast traffic intelligently, instead of flooding it out all ports in the VLAN. Without MLD snooping, multicast group membership for VLAN aware devices is on a per-VLAN basis, because MLD is an IPv6-based protocol. If at least one port in the VLAN is a member of a multicast group, and MLD sn
Summary of the content on the page No. 16
16 Patch Release Note MLD snooping on the switch uses the last 4 bytes of the IPv6 address to distinguish multicast addresses. It is therefore unable to distinguish different multicast addresses that end with the same 4 bytes. Creating an entry for a multicast group will have the effect of creating an entry for all groups with addresses that end with the same 4 bytes as that group’s address. For example, traffic for the groups: ffxx xxxx xxxx xxxx xxxx xxxx 1234 5678 and ffyy yyyy yyyy yyy
