Maintenance #101: VSIMgr. ID size • Problem: ieee 8021 Bridge. Evb. VSIMgr. ID object defines an octet string object with size 1, with a reference to subclause 41. 1. 3 'VSI Manager ID'. However this subclause states that 'The value 0 means. . . indicating that the Bridge should select a default value. Any other value is interpreted as an IPv 6 address, as defined in IETF RFC 4291. ' In addition the 'VSI Mgr ID' field in the VSI manager ID TLV is defined as 16 octets. This seems to imply the object size should be 16 bytes. • Recommendation: Ieee 8021 Bridge. Evb. VSIMgr. ID size should be 16 octets not 1 octet. Need to deprecate MIB object and define a new object in the same row with a new name (i. e. ieee 8021 Bridge. Evb. VSIMgr. ID 16).

Maintenance #? ? ? : VSIMv. Format Size • Problem: The values for ieee 8021 Bridge. Evb. VSIMv. Format object are 'basic (1)', 'partial (2)', and 'vlan. Only (3)‘, however the reference for this object is subclause 41. 2. 8 'Filter Info format' which states 'The Filter Info formats defined by this standard are shown in Table 41 -6. '. Table 41 -6 however defines values of 'VID (41. 2. 9. 1) 0 x 01', 'MAC/VID (41. 2. 9. 2) 0 x 02', 'Group. ID/VID (41. 2. 9. 3) 0 x 03' and 'Group. ID/MAC/VID (41. 2. 9. 4) 0 x 04' which don't match the object vales. • Recommendation: The value list should match Table 41 -6. Deprecate the object, create a new one with new name (i. e. VSIMv. Format 4). 3 9/11/2021 EVB

Maintenance #? ? ? : ieee 8021 Bridge. Evb. VDPCounter. Discontinuit y • Problem: The description for the ieee 8021 Bridge. Evb. VDPCounter. Discontinuity object is 'The time (in hundredths of a second) since the last counter discontinuity. ' and while I assume it is either associated with, or derived from, if. Counter. Discontinuity. Time there appears to be no further definition of this object and there is no reference subclause. • Recommendation: The discontinuity referred to is VSIDBEntry creations which can occur at any time since these entries can be created and destroyed dynamically along with the VDP machine instances. The timer which may have a discontinuity is the ieee 8021 Bridge. Evb. VSITime. Since. Create. Some text should be added to the VDPCounter. Discontinuity indicating that it is set when the VSIDBEntry is created. At very least the description should be improved, possibly the MIB items should be removed. 4 9/11/2021 EVB

Maintenance #? ? ? : • Problem: Clause 12 specifies object called evb. Sys. Ecp. Dflt. Ack. Timer. Init and evb. Sys. Ecp. Dflt. Max. Tries, however clause 17 references objects by the names ieee 8021 Bridge. Evb. Sys. Ecp. Ack. Timer and ieee 8021 Bridge. Evb. Sys. Ecp. Max. Tries in table 17 -26 and ieee 8021 Bridge. Evb. Sys. Ecp. Max. Retries in the MIB text. These names should be alligned and Max. Tries should be relaced with Max. Retries. • PROPOSED REVISION TEXT: − Replace evb. Sys. Ecp. Dftl. Max. Tries in clause 12 and table 12 -17 with evb. Sys. Ecp. Dflt. Max. Retries. − Replace ieee 8021 Bridge. Evb. Sys. Ecp. Ack. Timer and ieee 8021 Bridge. Evb. Sys. Ecp. Max. Tries in table 17 -26 with ieee 8021 Bridge. Evb. Sys. Ecp. Dflt. Ack. Timer. Init and ieee 8021 Bridge. Evb. Sys. Ecp. Dflt. Max. Retries. − Deprecate ieee 8021 Bridge. Evb. Sys. Ecp. Ack. Timer and ieee 8021 Bridge. Evb. Sys. Ecp. Max. Retries from the SNMP MIB and add new replacement objects called ieee 8021 Bridge. Evb. Sys. Ecp. Dflt. Ack. Timer. Init and ieee 8021 Bridge. Evb. Sys. Ecp. Dflt. Max. Retries. 5 9/11/2021 EVB

Resolution for #91 annex D Annex D. 2. 13. 6, D. 2. 13. 8, D. 2. 13. 9 needs to be changed to exclude the 10 x factor when setting the ECP and VDP timer initialization values to match the VDP and ECP timer units of 10 usec. • For D. 2. 13. 6 remove the 10 x in the equation changing the units to “VDP timer tics”. Also change the last sentence to “…greater of 8 (2. 56 ms) and local value for RTE is used. ” • For D. 2. 13. 8 remove the 10 x in the equation changing the units to “VDP timer tics”. • For D. 2. 13. 9 remove the 10 x in the equation changing the units to “VDP timer tics”. • 8 9/11/2021 EVB

Resolution for #91 clause 41 Since VDP timers have a resolution of 10 usec (41. 5. 4) the variables tout. Keep. Alive (41. 5. 5. 12) and resp. Wait. Delay (41. 5. 5. 9) should be in units of time tic (10 usec), and the equations should not include the 10 x multiplier. Need to add units of “timer tics” to the two equations. • Replace resp. Wait. Delay equation with • • resp. Wait. Delay = 1. 5 x (resource. Wait. Delay + (2 x ecp. Oper. Max. Tries + 1) x ecp. Oper. Ack. Timer. Init) tics • Replace the default value with 17. 4 seconds • Replace tout. Keep. Alive equation with tout. Keep. Alive = 1. 5 x (reinit. Keep. Alive + (2 x ecp. Oper. Max. Tries + 1) x ecp. Oper. Ack. Timer. Init) tics • Replace the default value with 17. 4 seconds • 9 9/11/2021 EVB
