---|---|---|---|
3903 | All | cnMaestro/Port Channel | cnMaestro configuration sync fails when there is more than one port channel configured on Switch Port page |

Known Issues
Tracking | Product | Description | Workaround |
---|---|---|---|
388 | All | DHCP Relay: The switch doesn’t relay all DHCP Release and Renew packets if there are more than 360 DHCP clients connected to the switch. | Use cnMatrix switch to relay DHCP packets for less than 360 DHCP clients. |
460 | All | LLDP port-id-subtype setting, and DHCP server host hardware-type 3 setting are lost after boot. | Reconfigure the settings if they are lost after reboot. |
519 | All | UP7 traffic not equally serviced if received from 2 different ports - SP scheduler | N/A |
695 | All | Ping doesn’t work between 1/10 Gb interfaces or 1/10 Gb port-channels when STP mode is PVRST and more than 9 VLANs are created. | N/A |
838 | All | DHCP Snooping: When disabling DHCP Snooping globally, the DHCP Snooping VLAN configuration is cleared. | Reconfigure DHCP Snooping per VLAN. |
848 | All | Auto Attach: For phone detection it is advisable not to use rules with LLDP-CAP “phone” as matching criteria. | Phones can be identified using other data LLDP data, such as System Description, System Name or Chassis ID. |
946 | All | Routing is not working on routed port when static ARP is used | Use static ARPs only for VLAN interfaces. |
985 | All | Exec-timeout setting is lost after reboot. | Reconfigure this setting after unit reboot. |
1056 | All | Physical ports that are part of a port-channel are returning to VLAN 1 after remote peer is performing a boot default. 1) When port-channel is deleted, links are not restored to original VLANs 2) When link member is not part of the bundle, it is assigned to VLAN 1 |
N/A |
1555 | All | When downloading agent using SFTP from SSH/telnet session, the download progress is displayed on the console interface, not in the current session. | N/A |
1828 | All | Establishing a SSH session between two cnMatrix devices is not working. | Enable SSH HMAC LIST ( HMAC- MD5 / HMAC-SHA1 ) on the cnMatrix acting as a SSH server |
2103 | All / CnMaestro | Router Port configuration from CLI Templates will result in faulty port performance tracking | N/A |
2122 | All | RIPv1/RIPv1 compatible updates are not sent to the RIP neighbors (3.0.1-r4 does not work with RIPv1 RIP router) | Only connect cnMatrix 3.0.1-r4 to RIPv2 neighbors, and set the RIP send update to RIPv2 mode |
3669 | All | 802.1x : Single Host – MAC address of the client is learnt in all the VLANs configured on the switch | N/A |
3513 | All / cnMaestro | MSTP: In some cases, for very long VLAN lists associated to MSTP instances, the configuration may fail | N/A |
3514 | All / cnMaestro | MSTP: When the VLAN-instance mapping is updated, the user may experience a momentary traffic drop | N/A |
3646 | All | 802.1x: Vlan Priority Attribute can be configured on Radius server with the standard attribute User-Priority-Table and the value accepted is in the format “xxxxxxxx”. ( 8x ) | N/A |
3677 | All | 802.1x : Single Host - Multiple hosts can be authenticated on the same port | N/A |
3586 | All | Storm-control not working correctly on a SFP+ port with 1G transceiver. Packet are limited on that port at a rate 10 time grater than for a 1G port. | N/A |
3683 | All | Port MAC Limiting: Migrated MAC addresses are not deleted from the software FDB table after the limit is reached on the new port. | This is a display issue. Please ignore this output. |
3772, 3775, 4111 | TX1K/TX2K | PoE – ports configured in hybrid or passive-54V mode do not power-up any devices unless the maximum power capability of the port is available in the power budget (i.e. 90w for the 4-Pair ports and 30w for the rest) regardless of how much power the inserted devices need to draw | N/A |
Feature Notes
- If you remove the default IP address from mgmt0 interface and save the running-config the default
IP address is restored after boot. - DHCP Client is enabled by default on In-Band Ports from VLAN 1.
- On EX1K and TX models, VLAN 1 has the default IP address 192.168.1.1
- The Out-of-Band port on EX2K has the following default IP address: 192.168.0.1.
Limitations
Tracking | Product | Description | Workaround |
---|---|---|---|
265 | Flow control counters displayed by the command show interface flow control are not incremented on Extreme Ethernet interfaces (10Gbps). |
||
437 | All | SNTP Authentication is not supported for broadcast and multicast modes. | |
2103 | All | Router Port configuration from CLI Templates will result in faulty port performance tracking | Configuring a router port from a template can lead to unexpected monitoring behavior. The setting is not recommended while using cnMaestro. |
2603 | All | If a static IP is set on L3 interface from CLI/Web, the out-of-sync condition is not triggered by cnMaestro. |
