There is an inconsistency between CLI and EDM in release 5.9 which results in an EDM error Wrong Value when select 802.3at and 32w on a port.
See attached solution note from Avaya support webpage.
This issue was fixed in release 5.10. Upgrading the switch to the latest release should eliminate this error. Upgraded switch to 5.12.3 release. The option in EDM for 802.3at has been removed.
It is possible to set 32w of power on a port configured as 802.3af on the Avaya ERS 4850 as a PWR+ switch supports 802.3at.
If still have issues negotiating power with a PD then try to use LLDP on the PSE and PD.
Below are the power related commands that can be enabled.
Switch(config)Interface ethernet 1/13
Switch(config-if)#lldp status txAndRx config-notification
Switch(config-if)#lldp tx-tlv port 1/13 dot3 mdi-power-support
Switch(config-if)#lldp tx-tlv port 1/13 med med-capabilities
Switch(config-if)#lldp tx-tlv port 1/13 med extendedPSE
The AP must have LLDP enabled also so they can exchange LLDPDUs. This note relates to the experience found providing the power demanded for an Aerohive 650 Access Point on an Avaya ERS 4850GTS-PWR+ switch.
Use Autonegotiation to allow the device to automatically negotiate the best common data rate and duplex mode to use between two Autonegotiation-capable Ethernet devices.
When you use a 1 Gigabit SFP transceiver on a 10 Gigabit SFP+ port, you must enable autonegotiate if it is not enabled already. However, if you use 1 Gigabit SFP transceivers on a VSP 4000 switch that is connected to third party switches at the remote end, you must have autonegotiate enabled at all times; this applies to SFP transceivers installed in a 1 Gigabit SFP port or a 10 Gigabit SFP+ port.
For VSP 7254XSQ, auto-negotiation is always disabled for 1 Gigabit Ethernet transceivers. If using a 1000BASE-T SFP, the remote 1000BASE-T interface must have auto-negotiation enabled. If not, the link will not be established. Also note that because the SFP+ ports on the VSP 7254XSQ only support 1 and 10 Gbps speeds, the AA1419043-E6 1000BASE-T SFP will only operate at 1G speeds.
If you use 1 Gbps fiber SFP transceivers, auto-negotiation is always disabled so the remote end must also have auto-negotiation disabled. Otherwise this is not a supported configuration with VSP 7254XSQ.
Connecting VSP 7254XSQ with 1 Gbps fiber SFP to EXOS switches will require autonegotiation to be disabled on EXOS switch.
